Can a pregnancy test be used to determine ovulation? Tests to determine ovulation - a modern approach to the problem of conception

Collapse

An ovulation test is a reliable way to find out when there is a chance or risk of pregnancy. Such tests are very convenient to plan pregnancy. Ovulation in women occurs individually, depending on changes in the hormonal background, so you can determine exactly when it occurred using a test. But this is not a 100% conception planning method, as it sometimes fails.

Can the test be wrong?

In any methods of contraception or diagnostics, there is a possibility of error. Can an ovulation test be wrong? Unfortunately, maybe. This happens for various reasons, depending on its use and quality.

Why doesn't an ovulation test show it?

There are situations when everything is done according to the instructions, but the test is “silent” and shows nothing. Women who are expecting a baby cannot wait until this cherished period of the possibility of conceiving a baby comes, and they take additional tests. But this is not always justified, and it is costly. So why doesn't an ovulation test show ovulation?

bad test

Such tests are not as common as pregnancy tests, because of this you have to buy what is in the pharmacy. And it may not be a quality product. Tests differ in cost and characteristics, their reliability also depends on this.

The most accurate is the digital test. Also, when choosing between a test strip and a test tablet, the advantage should be given to the test tablet - it is more reliable.

If you fall for an unscrupulous manufacturer, there may be problems with determining the ovulation period, since the reagent is of poor quality.

Test rules violated

Each type of device has its own characteristics, but there are general recommendations for their storage and use. The reasons for incorrect test results are sometimes in violation of the instructions for using the device.

The test must be kept closed and should only be printed before use.
Be sure to look at the expiration date - the reagent after the expiration date may not perform its function.
No need to use the first urine. Urine collected after 10 a.m. and before 8 p.m. is suitable for testing.
Test strips and test plates are disposable and cannot be used multiple times.
In order for the result to be the most correct, two hours before testing, it is necessary to limit the intake of fluid into the body.
The test strip must be held vertically in the urine for 5 seconds, not higher than the indicated line. In ten minutes, the results will be ready.
The control band must appear - this is an indicator of a correctly conducted test.
If ovulation has occurred, the strip that is located with the control should be the same or brighter in brightness.
If the line is very bright, this is an indication that the test was performed on the first day of ovulation.

To determine the exact date of ovulation, testing should be done every day until there are two bright stripes.

No ovulation

An ovulation test is not always negative due to procedure errors and unscrupulous manufacturers. The lack of the desired result is possible due to the anovulatory cycle. Such cycles are not accompanied by the release of an egg from the ovary, so ovulation does not occur.

At a young age, anovulatory cycles almost never happen. In middle age, women experience such periods more often. The stock of eggs decreases with age, and therefore the reproductive possibilities of a woman decrease.

Anovulatory periods may also occur outside of natural periods. This may be the result of taking hormonal drugs. If a woman takes oral contraceptives, it makes no sense to “catch” ovulation, since this process is blocked.

What to do if ovulation is not determined?

What to do if constant attempts to determine ovulation were in vain? We considered the possible reasons for the lack of results during testing. If ovulation is not detected, all these causes must be excluded.

Bad test - replace. If the test strip does not show the period of release of the egg from the ovary, this is not a reason to panic, perhaps another type of test will be more sensitive to luteinizing hormone. Therefore, you need to try a different kind of test.
Violation of the rules of use - carefully study the instructions. The procedure must be done strictly according to the instructions in order to obtain an accurate result. Perhaps something is done wrong.
No ovulation - this phenomenon may indicate hormonal therapy (if such is carried out, it must be canceled to achieve a result), age-related changes, incorrectly chosen testing time, and a pathological process in the woman's reproductive system. In each case, there must be action to overcome these factors.

Not always the cause of anovulation should be sought in the test. Often this problem occurs due to violations in the reproductive system of a woman. It is necessary to start treating anovulation with the therapy of inflammatory processes. For this, different groups of drugs are used: antibacterial, antifungal, antiviral agents. After antibiotics, the entire flora on the mucous membranes suffers: intestinal, vaginal, and so on. Immunomodulatory agents are sometimes required to restore a woman's health. Indeed, vaginal dysbacteriosis is a common cause of infertility.

To stimulate ovulation, hormonal drugs are prescribed, so any such treatment should be with the permission of a doctor. Common drugs are Gonal and Klostilbegit.

conclusions

Ovulation tests are a great way to help plan your pregnancy. They do not show the ovulatory period for several objective and subjective reasons.

You can achieve the desired two red stripes on the test by the following actions: change the test, carefully study the instructions for use and do everything right, stop taking oral contraceptives, apply drug therapy for anovulation, calculate the correct time for testing.

An ovulation test is a fairly accurate method for determining ovulation, but only when used correctly.

Ovulation test instructions

Ovulation tests are different, but their principle of operation is the same, which means that the instructions are generally similar.

Keep closed. Print the test only immediately before use
Check the expiration date
For the test, do not use the first morning urine
Do not use the same test more than once
Learn how to use the test to avoid false positives

How to use:

Urine collected between 10 am and 8 pm is best for testing.
Reduce fluid intake 2 hours before using the test
If you have a classic test strip at your disposal, then lower it vertically into a container of urine to the line indicated on it. Hold for 5 seconds. Place the test on a flat and dry surface. Evaluate the result after 10 minutes
You should definitely see the control strip. This will indicate a correct test.
Next to the control you will see a second strip: weak or bright. The result strip will then indicate a positive outcome of the test when it is the same brightness or brighter than the control
Such a strip indicates that ovulation will occur within 24 hours.
If you bought an electronic test, then read more about it in section 6 "Electronic ovulation test"

IMPORTANT: Test daily, starting from a certain day and do until you see the desired result.

How does an ovulation test work?

Shortly before ovulation, the body begins to produce luteinizing hormone. It is this hormone that is determined by the ovulation test.
If the hormone began to be produced in the body, then ovulation is about to come, which means that the test will show a brighter strip
Accordingly, if there is no hormone, then the result strip will not become brighter than the control strip

When is the best time to do an ovulation test?

The day you should start testing depends on your menstrual cycle. Read more in the section "How to calculate the ovulation cycle" of the article.

Ovulation test morning and evening

So in this way, in the morning you can see a weak strip, and in the evening there is already a bright positive result.

Reusable ovulation test

A reusable ovulation test is a kit:

USB device
20 (typically) test strips

The test is both an ovulation test and a pregnancy test at the same time, as it determines both the level of hCG and luteinizing hormone.

The test is like a USB flash drive into which a test strip is inserted. The screen displays the hCG and luteinizing hormone levels. Further, the device can be connected to a computer to obtain statistical data about your tests (track the dynamics).

Such tests cost a lot and are quite difficult to find.

Electronic ovulation test

Manufacturers position electronic ovulation tests as the most accurate, namely 99% accuracy. Tests show the 2 most successful days for conception.

The test is done with a test strip, which is inserted into the cassette for reading information. Read the instructions carefully before use. It may vary slightly from manufacturer to manufacturer.

See below for a video on how to use these tests.

Can an ovulation test show pregnancy?

The reagent impregnated with an ovulation test reacts to luteinizing hormone. After ovulation has occurred, the hormone ceases to be produced in such quantities, even in case of pregnancy
Pregnancy brings with it a high level of hCG. Pregnancy tests are just soaked with such reagents that react to this hormone
An ovulation test is not impregnated with such reagents, which means it cannot be proof of pregnancy.
If you took an ovulation test while pregnant and it showed a positive result, then this is definitely not related to pregnancy. There are other reasons for false positive tests.

Positive ovulation test

A positive ovulation test on simple test strips will be when you see the same bright or brighter result strip next to the control strip.

Electronic tests show a certain icon in the window, indicating the onset of ovulation in the next 24 hours. An example would be the "Smile" icon in the Clearblue test.

Sometimes the test may show a false positive result:

If you did not urinate for a long time before the test, as the concentration of the hormone in the urine will be unreasonably increased. Therefore, you should not do the test using the first morning urine.
If the hormonal background is disturbed. A hormonal failure in the body always gives an unpredictable result, not only on an ovulation test, but also when measuring basal temperature, and in the presence of discharge and other signs of ovulation
If you did an hCG angle
If you were taking hormonal drugs, including contraceptives
kidney disease
Sudden change in the power system

Weak line on ovulation test

A faint line is not a positive result. This is due to the fact that luteinizing hormone in small quantities can be produced by the body at any time of the cycle. And only 24-48 hours before ovulation, it is thrown out in large quantities. The test reacts to this outlier, showing a bright strip.

Ovulation Test During Pregnancy

An ovulation test during pregnancy should not show a positive result. Read the reasons above for details.

Why is an ovulation test always negative?

Causes negative tests:

Drinking large amounts of liquid before the test. This is due to the fact that the liquid reduces the concentration of the hormone in the urine, as a result of which it may not respond
Poor quality tests
Incorrect use of the test
anovulation

anovulation- this is a condition when ovulation does not occur. Anovulation happens in two cases:

Health problems. Then you should contact an experienced gynecologist for treatment
Pregnancy, breastfeeding, menopause

Signs that are present worth going to the doctor rather than look for the cause as tests:

Menstruation is too scanty or too profuse
In the expected period of ovulation, there is no heavy discharge
Basal body temperature readings show constant spikes or sustained low temperature throughout cycle (more than 2 months in a row)

Ovulation test positive: when is conception?

The test shows a positive result when the luteinizing hormone is released into the blood. This happens on average 24 hours before ovulation.

Therefore, conception should occur within the next few hours after receiving a positive ovulation test result.

Spermatozoa will enter the abdominal cavity and wait for the release of the egg, as they live an average of 3-4 days.

Follow the instructions for using ovulation tests and then this method will be very accurate for determining ovulation.

Video: Ovulation test

An ovulation test strip allows you to determine the days on which a woman is most ready to conceive. They appeared relatively recently, and few know about them. But women who cannot get pregnant in any way use this diagnostic tool to determine the time of ovulation, significantly increasing the chances of conception.

The principle of determining ovulation using a test

In every healthy woman, immediately after the next menstruation, a new egg begins to mature (sometimes 2 or more). Before the maturation and immediate release of the egg from the ovary, significant hormonal changes occur in the female body: an increase in the level of hormones responsible for readiness for subsequent fertilization is found in the blood (see).

One of them is called luteinizing hormone (LH) and can be detected by diagnostic methods both in the blood and in other body fluids - saliva, urine. Home diagnostics is based on the definition of this hormone: a positive ovulation test will indicate that the egg is already mature and ready for conception.

When to do an ovulation test

The time of the test is calculated depending on the duration of the menstrual cycle. Diagnostics is carried out for five days in a row, without gaps, in the morning and evening with double testing or only in the morning.

With a 28-day cycle, you can test from day 11, which is counted from the first day of the last menstruation.
If the cycle is more than 28 days, the diagnosis begins 17 days before the expected first day of the next menstruation.
With an irregular cycle, the shortest cycle that the woman had was taken as the initial figure, for example:
- with a 32-day cycle, start testing from the 15th day
- at 24 days: from day 7
- at 26 days: from the 9th day from the first day of menstruation, etc.

Does ovulation always occur in the middle of the cycle?

Even in absolutely healthy women with a regular cycle, ovulation does not always fall in its middle: this is evidenced by thousands of born children, whose conception occurred on the so-called safe days before or after menstruation. Ovulation is affected by stress, infections, climate change, and more. Therefore, it is possible to “catch” a high level of LH both earlier and later than the dates indicated above, if this is really important for a woman.

Types of tests, diagnostic features

Outwardly, ovulation tests are similar to those for determining pregnancy; urine is also used for diagnosis. Test manufacturers produce different types of diagnostic systems that have different price characteristics and reliability.

Strip test or test strip

The most common paper test with a reagent applied to it and a control strip. The test is lowered into a dry and clean bowl with freshly collected urine for 10 seconds, then you should wait for the result within 5-10 minutes.

With an elevated LH level, a second strip will be visible on the strip.
It can be visible from the first day of diagnosis, but one can speak of a reliable readiness for conception with the color and severity of the second strip, the same as the control one (usually it is 3-4 days of diagnosis).

Test tablet

This system is a plastic case with small control windows: urine should be dropped into the first window, the result will be visible in the other after a short time (2-3 minutes), the same 2 strips at a high level of LH. The reliability of tablet tests is rated higher than that of test strips.

Inkjet rapid test

This system is represented by a strip coated with a special reagent with a control strip. For diagnosis, you do not need to collect urine: the strip is simply substituted under the stream of urine. The result is evaluated after 3-5 minutes. What the ovulation test shows - with a high level of LH, 2 strips will be visible.

Portable reusable systems

They consist of a control electronic device and strips designed to be immersed in freshly collected urine. They are highly informative and allow diagnostics to be carried out on different days of the cycle, allowing you to determine the most suitable time for conception.

Digital ovulation test

A highly informative reusable system that uses a woman's saliva, which changes its physical properties during the cycle. The most accurate diagnostics, eliminating the error. In fact, it is a mini-microscope, it looks like lipstick.

With the help of a miniature magnifying device, a specific pattern can be seen in the examined saliva, similar to a fern leaf or a frosty pattern. This pattern appears only before the release of the egg.

Features of the use of home express diagnostics for determining ovulation

It should be understood that the test does not directly indicate the release of the egg from the ovary, but only captures an increased level of LH. Those. with a positive ovulation test, a hormonal surge is noted, which indicates the release of a mature egg in the coming hours.
The highest level of LH is kept for less than a day, so it is recommended to carry out diagnostics 2 times a day (morning and evening) in order to be more likely to catch this moment.
You should not drink a lot of liquid three to four hours before testing, so as not to dilute the urine.
When using a digital saliva test, be sure to compare the result with the control picture.

Negative test

Determined if ovulation is still far away.
An ovulation test after ovulation will also be negative - after the release of the egg from the ovary, the LH level drops.
An expired, damaged, poor-quality ovulation test can also show 1 line when there is actually a high level of LH.

When should I start conceiving directly after a positive ovulation test?

This question worries everyone, but the instructions for the ovulation test do not contain such information, and not everyone is able to ask the doctor directly. So, let's figure it out:

A positive test tells us that in the next few hours the egg will come out of the ovary, mature and ready for fertilization.
The egg cell lives only 24 hours after leaving the gonad.
Thus, it is not worth starting conception immediately after a positive test, you need to pause for several hours, allowing the egg to leave the ovary. Optimal time: 5-10 hours after diagnosis, not forgetting that the egg lives only a day.
It is not worth delaying this moment for the last hours of the cherished day, since fertilization itself does not occur immediately immediately after sexual intercourse, but after several hours, during which the sex cells move towards each other.

How to increase the chances of conceiving a boy or girl?

It is known that if an egg is fertilized by a sperm with an X chromosome, then a female embryo develops, if a sperm with a Y chromosome develops a male. There is also a theory that sperm with X and Y chromosomes have different characteristics, which increase the chances of conceiving a child of the desired sex.

It is known that spermatozoa live from 1 to 4.5 days, and spermatozoa with the Y chromosome (boy) live no more than 1-2 days, but move faster than spermatozoa with the X chromosome (girl). The spermatozoa that lead to the conception of a girl are more hardy and can survive up to 5 days in anticipation of ovulation, but are less mobile. That is, if sexual intercourse is performed at the very peak of ovulation, spermatozoa Y (boy) will reach the “target” faster and then the probability of having a boy is very high.

So, to conceive a boy, it is desirable:

Refuse sexual intercourse 4-5 days before the expected ovulation.
Have intercourse on the day when the ovulation test is positive
Intercourse penetration is preferably "deep", which will shorten the path of Y spermatozoa (living so shortly) to the egg.
Men should not experience overheating, because the increased temperature caused by warm clothes, sauna, etc., leads to a decrease in the number of spermatozoa (it is believed that Y spermatozoa die faster from overheating).

To conceive a girl, it is desirable:

Schedule sexual intercourse approximately 2-3 days before expected ovulation and do not have sexual intercourse during and for 2-3 days after ovulation.
In this case, the chances of survival in X spermatozoa are higher than in Y spermatozoa.
Penetration should be shallow, which will reduce the chances of reaching the goal of sperm, resulting in the conception of boys, and X sperm will survive and be able to get to the egg in these few days.

Method for measuring basal temperature

It is also one of the ways to determine ovulation, unlike the test - it does not require spending money, but only requires regular measurement of temperature in the rectum (every morning before getting out of bed). After menstruation, the basal temperature is usually below 37C, but in the middle of the cycle before ovulation it decreases, and then, if ovulation has occurred, the temperature rises to 37.3-37.6C. The measurement results should be recorded and plotted, this will help the woman determine whether she ovulated and on what day.

Does an ovulation test show pregnancy?

Among the forum members of various women's portals, this topic is hotly discussed, moreover, some of them claim that the ovulation test showed them pregnancy from the first days of conception, while the usual one was negative.

It should be understood that this is not possible. After ovulation is completed, the ovulation test becomes negative, regardless of whether the woman is pregnant or not. All pregnancy and ovulation tests capture different hormones: hCG and LH, and cannot react to each other.

From this we conclude that the ovulation test will not show pregnancy, and 2 strips on it are evidence of impending ovulation (that is, the time when there is a chance to get pregnant), but not pregnancy.

What else is this test used for?

To prevent pregnancy during unprotected intercourse. A controversial method, since it requires constant testing, which is not always economically feasible, but still practiced. If even a weak second strip appears, you should switch to protected intercourse until the second day after the strip completely disappears. However, there is no guarantee.

Can I do ovulation tests every day?

It is absolutely harmless, and if the budget allows - why not. This behavior is typical for, or if it is suspected. You should not be so obsessively expecting a miracle and endlessly doing tests, but it’s better to calm down and, so to speak, “let go of the situation” - and then the cherished 2 stripes will definitely be highlighted already on the test for diagnosing pregnancy.

Overview of popular ovulation tests

Despite the same mechanism of action, ovulation tests from different manufacturers differ in the reliability of the result. Women have the greatest confidence in 3 manufacturers, a wide range of diagnostic systems of which are presented in pharmacies and retail chains: Frautest, Eviplan and Clearblue.

Frautest

The manufacturer produces three lines of diagnostic tests to determine ovulation. All of them are characterized by a high degree of reliability:


Ovulation: 5 test strips, suitable for women with regular cycles. The price is about 300 rubles.	Planning: 5 ovulation test strips (same as Ovulation) and 2 pregnancy tests. The price is about 420 rubles.	Ovulation test cassettes: 7 tests suitable for women with irregular cycles. The price is about 750 rubles.

Eviplan Clearblue


The Eviplan ovulation test No. 5 includes 5 diagnostic strips and 1 pregnancy test. The reliability is high, the same as that of Frautest, but the cost is less, about 310 rubles.	Clearblue Ovulation Test - This digital test kit includes an electronic reader and 7 control strips. The e-reader will show a smiley face if the result is positive. The price is about 1000 rubles.

Lady-Q, INSURE, OVUPLAN


A digital reusable device that promises 100% accuracy. The woman's saliva is used. Includes: microscope, removable glass, instructions and control drawings. The price is about 2000 rubles.	Domestic test strips (5 pieces per set), promising 99% reliable results. They are chosen due to the low price - 150 rubles.	Inkjet test strips, 99% reliable, but less popular among women. The price is about 200 rubles.

Women who dream of having a child do not always manage to get pregnant. Help in this situation is provided by an ovulation test, which, by changing the color of the strip, determines the time of probable fertilization of the egg by the sperm - if everything is done correctly. What is the principle of operation of such an express analysis, how high is its accuracy, which is shown by the results of the test - women planning to conceive should know about this.

What is an ovulation test

Information about the fertilization period of the egg is important for those who want to have a baby. The ovulation period is the time when the probability of conception is maximum. There are exact methods for determining it using special tests. You just need to know the features of the female body:

after the end of menstruation, the ovarian follicle matures;
under the influence of female hormones, an egg develops;
important changes are being made;
The release of the egg from the ovary is preceded by the release of hormones responsible for the fertilization process.

One of these important chemicals has a maximum concentration during this period. This is luteinizing hormone (LH) which is determined using diagnostic techniques. It is found in the blood and fluids such as urine and saliva. The principle of operation of tests that determine reliable timing of ovulation is based on the indirect determination of the concentration of the LH hormone. As a result of such home diagnostics:

positive - indicates a mature egg, a high probability of pregnancy;
negative - a sign of the absence of conception.

How does it work

It is interesting to understand how ovulation tests work. When the strips or cassettes come into contact with urine, which contains an increased amount of hormones, a reaction occurs. The components applied to the samples begin to interact with LG. It is important to know:

an increase in hormones is observed during the day, so it is recommended to analyze in the morning and in the evening;
if saliva begins to react with a digital test, the result is checked against a reference sample;
a positive result - a signal to act - to start having sex with a sexual partner to conceive a child.

What shows

How to determine ovulation by test and the period when pregnancy is highly likely? Diagnostics may show different results. When comparing the control strip and the result of the express analysis, a positive result is noted:

a sign of ovulation - the color of the lines is the same in tone or brighter;
the egg is ready for fertilization in the near future;
the optimal time for conception is 6 hours after the test.

A negative fact is noted if the line is not visible or a faint strip is observed. The result of such a diagnosis is interpreted as follows:

there is still a lot of time left before ovulation;
the egg has already left the ovary, the level of luteinizing hormone has dropped;
the test is defective, damaged or expired - while the concentration of LH in the urine may be increased.

When to do an ovulation test

When is the best time to get tested to plan a pregnancy? It depends on the length of the menstrual cycle. The calculation of time is taken from the first day of the last menstruation. It is advisable to check urine samples daily, morning and evening. The ovulation test instruction recommends for the duration of the cycle:

28 days - start testing from 11;
if the cycle is irregular, the shortest is taken as the basis;
with a longer duration - calculate the beginning of the first day of the next cycle and subtract 17 days.

Types of tests

Most testing methods, like pregnancy testing, use urine. The methods are based on fixing the increase in the level of hormones before the release of the egg. Diagnostic tools differ in reliability, price, convenience. Manufacturers produce test strips with low accuracy, suitable for women with a regular cycle.

More accurate results are obtained by using devices that have increased accuracy and reliability. Popularity is:

reusable means with a set of test strips;
electronic devices that react to saliva;
inkjet tests that determine the elevated level of hormones in the urine stream;
a complex of a small microscope and illumination, in which the pattern on the glass changes, depending on the concentration of salts in saliva, is compared with the standard.

Often, a simple method is used to determine the time of release of the egg from the ovary - compiling an ovulation calendar. It is based on the measurement of basal temperature, which changes during the cycle. After menstruation, it is less than 37, decreases before ovulation, and then rises to 37.6. A woman needs:

daily in the morning, lying in bed, check the temperature in the rectum;
record results;
build a graph of temperature changes;
the maximum points will indicate the desired days;
information is important for pregnancy planning.

test strips

The simplest and least expensive method of testing may offer a chance of getting pregnant if used by a woman who has a stable menstrual cycle of the same duration. It is based on the use of strips with a reagent applied to them and a red control line. To carry out you need:

pour urine into a clean bowl;
lower a strip into it for a few seconds;
wait 10 minutes;
compare the resulting line with the color standard.

reusable

An original miniature device, similar to a tube of lipstick, is a system that determines with high accuracy the time of release of the egg. For analysis, saliva is used, which changes characteristics during the menstrual cycle. Examination with a microscope with illumination helps:

see a pattern that looks like a leaf of a plant;
compare it with the attached samples, typical for the period of peak hormones.

Jet

It is easy to check the release time of the egg with a jet device. For diagnostics, it is not required to collect the material in a special container. When running the test:

a device in a plastic case, with a reagent applied to it, is supplied under a stream of urine;
aged 5 minutes;
the result is determined by comparing the two lines.

Digital

The device with an electronic device works by analyzing the urine of a woman. It is allowed to conduct a sample with a jet or material in a clean vessel. During diagnostics:

the device turns on - the indicator lights up;
contacts with the tested liquid;
laid out on a flat surface;
when ready, an audible signal sounds;
the result is shown on the screen.

How to do it right

To get reliable results after testing, you need to carefully read the instructions for the test before use. Means may differ in application. Key recommendations:

test to be done daily at the same time;
collect urine in a clean vessel;
open;
withstand in urine;
put on a dry surface;
evaluate the result after 10 minutes.

What to Consider

In order to know with high accuracy the time of release of the egg, several conditions must be met. It is important to follow the recommendations specified by the manufacturer in the annotation. Points to be taken into account:

4 hours before the test, refrain from urinating;
do not drink a lot of water;
exclude the use of hormonal agents, even in the form of an ointment;
results are affected by hot weather;
testing every 12 hours will help determine the exact time of ovulation with high accuracy.

Instructions for use

In order for the test result to be correct, you need to know how to use the ovulation test. To do this, you must first read the instructions for use. It may have features depending on the brand of the tester. This is especially true for electronic devices and microscope devices. For test strips, we recommend:

collect urine in a clean bowl;
lower the strip to the mark;
hold for about 10 seconds.

The test result will be ready in a few minutes - depending on the type. There are features of express analysis:

the brighter the strip compared to the standard, the higher the likelihood of ovulation;
it is better to do the test in the morning, if necessary, repeat it in the evening;
with a weak line, when the strip is paler than the standard or completely absent, it is premature to wait for the onset of pregnancy.

Frautest

Frautest brand tests are distinguished by accurate results in just one minute. In order to choose the right agent for determining the concentration of LH, a number of points should be taken into account. Women should know:

in the absence of a regular cycle, you need to choose a cassette device for inkjet analysis - 7 probes are included;
with stable menstruation, strips are recommended - in a package of 5 pieces in sealed bags.

clear blue

The Polish company Clearblue produces tests that are highly accurate, occupy a high place in the rating of express analyzes. They are simple and reliable for home use, show the optimal days for conception. Tests are produced in several modifications:

strips with a special mark of the level of immersion in urine;
electronic test - informative and convenient;
a device with a screen where strips for inkjet analysis are attached.

Eviplan

The Eviplan brand produces products in the form of strips and cassettes for inkjet analysis of urine, which are distinguished by a higher accuracy of the result. The instruction notes the subtleties when using tests of this brand. You need to take into account:

control strips should not be omitted in the morning urine with a high concentration;
the content of the hormone will decrease if you drink a lot of water before the analysis;
The test should preferably be done in the middle of the day.

Ovuplan

The Canadian test for home use is distinguished by its availability, ease of use, and accuracy. The paper is coated with a special composition that changes color under the influence of urine. With a positive result, a bright red line appears. Ovuplan is sold in three forms:

one test strip in a foil pack;
for several days - 5 pieces;
OvuPlan Lux is an inkjet system.

best ovulation test

When a woman is faced with the question of choosing a method for determining ovulation, you can listen to the advice of doctors or the reviews of friends. To purchase tests that will be the best for a particular person, you need to consider a number of factors:

for women with a regular menstrual cycle, the simplest and cheapest with stripes is suitable;
for those who have problems with conception, it is better to choose a more expensive electronic device that is distinguished by accuracy or a reusable microscope.

Which test is the best can only be said by the woman who uses it. From the variety of proposed methods, preference should be given to:

accuracy - the higher, the better;
ease of implementation and evaluation of the result;
the convenience of the testing procedure and the availability of time for it;
cost - taking into account financial possibilities and the need for repeated analyzes.

Ovulation test positive but no ovulation

When planning a pregnancy, women, having applied a test to determine ovulation and received a positive response, suddenly realize that the desired event has not occurred. Why is this possible? Doctors explain that the increase in luteinizing hormone, which fixes the test, is not always associated with the expected ovulation. It may be caused.

Ovulation is the main stage of the menstrual cycle. This period is the most favorable for conceiving a child. It is desirable for a woman who dreams of a baby to know exactly when ovulation occurs in her body. To determine there are tests for ovulation.

Ovulation is the exit from the ovary of a mature egg, ready for fertilization. After ovulation within two days, a woman can become pregnant. If within 48 hours the egg is not fertilized, then it will die and you will have to wait for the next month to conceive a child. If there was sexual intercourse 3 days before ovulation, then there is also a chance to become pregnant, since the spermatozoa remain active for just so long and will be able to “wait” for the release of the egg from the ovary.

Ovulation occurs approximately on the 14th day of the menstrual cycle, if its duration is 28 days. However, this information should not be relied upon. The onset of ovulation depends on many individual factors. You can find out a more accurate time of ovulation with the help of special tests.

How the test works

Each menstrual cycle occurs the maturation of one follicle in the ovaries, less often - two or more. As the follicle cells mature, female hormones called estrogens are produced. The larger the follicle becomes, the more estrogen its cells produce.

When the level of these estrogens reaches a level that will be sufficient for ovulation, luteinizing hormone (abbreviated LH) is released, after which, within about one to two days, the follicle ruptures (or simply ovulation) and the egg, which is ready for fertilization, rushes directly into the fallopian tube - to meet with spermatozoa. The time of development of the follicle may differ somewhat not only in several different women, but even in the same one - in different cycles.

So, the action of modern ovulation tests is based on determining the moment of a sudden increase in the level of LH in the urine.

Determining the time of ovulation using tests

There are various methods and means by which you can determine the most favorable time for conceiving a baby. Special ovulation tests are very simple and easy to use. Each package contains instructions for an ovulation test.

With the help of tests, an increase in the level of luteinizing hormone (LH) can be determined. Its amount increases in the body 1-2 days before ovulation. A woman who wants to get pregnant should plan sexual contact with her partner at this time. Women who are not ready for pregnancy should use protection during this period.

You can buy an ovulation test at any pharmacy. Specialists can offer several products of various brands that differ in sensitivity. Prices for ovulation tests with instructions are quite high. Before buying, you can read reviews on the Internet about specific products or ask friends who have previously used ovulation tests for advice.

From what day should you use ovulation tests?

The start time of testing should be determined based on the length of your cycle. The very first day of the menstrual cycle is the day when menstruation began. Cycle length is the number of days elapsed from the very first day of the most recent period to the very first day of the next.

If your cycle is always regular, of the same length, then you should start doing ovulation tests seventeen days before the next period, because after ovulation, the corpus luteum phase lasts 12-16 days (on average - 14). For example, if the length of your menstrual cycle is 28 days, then testing should begin around the 11th day, and if 32, then from the 15th.

If the duration of the cycle is not constant, you need to choose the shortest cycle in the last six months and use its duration to accurately calculate the day when you need to start testing. In the presence of large delays and lack of regularity, the use of tests alone without additional monitoring of follicles and ovulation is not reasonable.

When used daily (or even better twice a day - morning and evening), ovulation tests give excellent results, especially when combined with ultrasound. When using ultrasound control, you can not waste tests in vain, but wait a while until the follicle can reach a size of about 18-20 millimeters and is able to ovulate. That's when you can confidently start doing daily tests.

Rules for an ovulation test

Before using an ovulation test, you need to determine the length of the menstrual cycle. To do this, you need to calculate the number of days that have elapsed from the first day of the previous menstruation to the first day of the next. With a regular cycle, tests can be started 17 days before the start of menstruation.

For example, if the cycle duration is 30 days, then you can start testing from day 13. If the cycle length is constantly changing, then you need to select the shortest cycle that has been in the last six months, and apply it to calculate the first day from which you will need to start using the tests.

To get reliable results after testing, you need to carefully read the instructions for the test before using it.

The test steps are as follows:

collect urine in a clean and dry container;
open the sealed bag with the dough;
place the test in urine up to a special mark for 5 seconds;
put the test on a dry and flat surface;
see results in 10 minutes.

When testing, several requirements must be met. The correctness of the subsequent result depends on them. Firstly, you do not need to use the very first morning urine for testing, since the level of the hormone is higher in the morning. As a result, the test result will be incorrect. An ovulation test should preferably be done at the same time every day. The most favorable period for testing is from 10 am to 8 pm.

Second, you should refrain from urinating for at least 4 hours before testing. Thirdly, before the test you should not drink a lot of liquid. Because of this, the amount of LH in the urine may decrease, and the test result will be unreliable. Fourth, you need to remove the test from the sealed package just before testing. Until the analysis is carried out, dirt or moisture should not get on it. Never touch the reaction zone with your hands. All these requirements are specified in the instructions for the Eviplan ovulation tests and other brands.

Interpretation of test results

To determine the test results, it is necessary to compare the control strip located at the edge of the test field with the test line. Both strips appear after analysis within a few minutes.

The result will be negative if the test line is not visible or is paler than the control strip. This will mean that the level of LH in the body has not increased, which means that ovulation has not yet occurred.

The result will be positive if the test line is darker than the control strip or is the same brightness. This will indicate a sharp release of LH and the onset of ovulation within 24-48 hours. Thus, the next 2 days after the increase in LH levels are the most suitable for conception. If sexual intercourse occurs within 48 hours, then the chance of getting pregnant will be maximum.

There are times when the control strip does not appear at all. Most likely, the test was defective or the testing was carried out incorrectly. That is why it is necessary to carefully read the information in the instructions for Solo ovulation tests and other means.

Erroneous results

Unfortunately, ovulation tests may not show ovulation itself, but only some change in the dynamics of LH levels. A sharp rise in LH is very characteristic of ovulation, but the rise of luteinizing hormone itself cannot give a 100% guarantee that this event is associated with ovulation and the latter has definitely taken place.

An increase in the amount of luteinizing hormone can also occur in other situations - with ovarian wasting syndrome, hormonal dysfunction, kidney failure, postmenopause and other disorders. Thus, with any permanent or temporary dysfunction (including immediately after the withdrawal of synthetic hormonal drugs or a sudden transition to a raw food/vegetarian diet), tests may show false positive results. In addition, false positive results are also possible under the influence of other hormones that are absolutely not associated with changes in LH levels.

For example, in the presence of a pregnancy hormone, tests can give a positive result due to some similarities in the molecular structure with LH (in structure, luteinizing hormone is similar to some other glycoprotein hormones - TSH, hCG, FSH), which many pregnant women have already been able to see for themselves women. That is, an ovulation test during pregnancy may well give a false positive result. When ovulation is stimulated after hCG injections, tests can also show a positive result, which is absolutely not associated with an increase in the content of luteinizing hormone.

Ovulation tests after hCG injections are absolutely not informative. It is possible that fluctuations of some other hormones (TSH, FSH) and even nutritional habits (phytohormones contained in plants) can also somewhat affect the results of such tests.

Therefore, in the absence of menstruation or if any hormonal disorders are suspected, you should not rely only on test results. In such cases, the timing and presence of ovulation should be determined using more reliable diagnostic methods. For example, with the help of ultrasound examination.

Ovulation tests are sold in many pharmacies and are presented there in a fairly wide range.

Types of tests

In modern pharmacies, tests designed to determine ovulation are presented as:

test strips. Most likely, you are already familiar with a similar type of pregnancy test - a thin strip of special paper that is impregnated with a special reagent. An ovulation test is a similar strip that should be immersed in urine for a while, after which the result will appear after a while. Such ovulation tests are not very accurate and have their drawbacks.
Test plates(or test cassettes). Similar tests also have analogues among pregnancy tests. The test tablet is a plastic case with a small window. This test must be substituted under a stream of urine or just drip a little urine on it - and after a few minutes you can see the result in the window. The test pads are very reliable, but they also cost a little more.
Inkjet tests. These are the most reliable ovulation tests currently available. This ovulation test is dropped directly into a container of urine or simply placed under a stream of urine - and after a few minutes you will be able to observe the result.
Reusable ovulation tests. In fact, they are a portable device with a whole set of test strips. These strips are lowered into the urine, then they are inserted into the device - and very soon it will be possible to find out the result.
Electronic ovulation tests. These tests "react" not to urine, but to the woman's saliva. A small amount of saliva should be placed under the lens, and then either look at a special sensor, or observe the pattern on the saliva through the microscope that comes with the lens. What a specific pattern means is written in the instructions. These ovulation tests are quite expensive, but in terms of reliability, they definitely have no competitors!

True, if you are going to do an ovulation test, you should remember that all of the above tests may not show the exact timing of ovulation, but the timing of the release of LH into the body, after which ovulation should occur. This must be taken into account when conducting such tests.

At the moment, several companies produce ovulation tests. The most famous among them are Frautest, Eviplan and Clearblue.

Frautest

The Frautest brand ovulation test is one of the most reliable ways to determine your LH surge period. The package contains 5 strips in sealed bags and instructions for the Frautest ovulation test. A woman with a regular menstrual cycle will need 5 days to determine the level of LH.

The instructions noted that a positive result can be seen 40 seconds after the end of testing. To confirm a negative result, you need to wait 10 minutes. There is no point in interpreting the test results later. The sensitivity of the test is 30 mIU/ml.

Under the Frautest brand, special kits with ovulation and pregnancy tests are also produced. They are very economical. One package contains 5 ovulation test strips, 2 pregnancy test strips, instructions for ovulation and pregnancy tests, 7 special containers for collecting urine.

There are also special Frautest cassettes that allow you to determine the level of LH. The package includes 7 test cassettes. This remedy is suitable for women with irregular menstrual cycles. Before use, be sure to read Frautest's instructions for ovulation, as the methods of using cassettes and strips are slightly different from each other. The test is very easy to use. It is not necessary to collect urine in a separate bowl. The receiving part of the cassette will need to be substituted under the stream of urine for a few seconds.

Eviplan

Under the brand name Eviplan, test strips are produced to determine ovulation. Their sensitivity is 25 mIU/ml. The instructions for the Eviplan ovulation test indicate that the result can be seen 5 minutes after testing.

Eviplan inkjet tests have the same sensitivity as the strips of this brand. One package contains 5 cassettes. They ensure hygienic testing and accurate results. In the detailed instructions you can find answers to all incomprehensible questions.

Solo

Pharmasco's Solo Inkjet Tests are one of the best tools for determining ovulation. Each package contains 5 tests. The instructions have a special table, thanks to which you can determine the specific day when you need to start testing. For most women, one pack is enough to determine the LH surge.

There is a mini-format of Solo tests. It is a set of 5 test strips. The package also includes a free sensitive pregnancy test and instructions for the Solo ovulation test. After ovulation and the proposed conception, it is advisable to conduct a pregnancy test a few days later.

clear blue

The Clearblue Digital Ovulation Test indicates a slight increase in LH levels, which usually occurs 24-36 hours before ovulation. This allows you to accurately determine the two most favorable days for conceiving a child in this cycle. Making love on these two days will give you many more opportunities to get pregnant than on any other days.

The Clearblue Ovulation Test is the most effective home test available.

The Clearblue Ovulation Test should be used on multiple days, at the same time each day, when Luteinizing Hormone levels are expected to rise. The test can determine the days of your cycle when your chances of conception are highest.

The Clearblue Ovulation Test has the following features:

Detects the very peak of LH concentration with 99% accuracy
Pretty easy to use, is a non-invasive and natural urine test
Has the original flashing test strip symbol to indicate that the test is working correctly
Shows results within three minutes

The cost of ovulation tests produced by this company is about 700 rubles.

Benefits of ovulation tests

With ovulation tests, it is more convenient for a woman to plan her personal life. With the help of them, you can determine the favorable time for conception and sexual intercourse. No need to measure rectal temperature, draw special graphics and perform complex procedures. It is enough to immerse the test strip in a container with urine or substitute the cassette under a stream of urine.

Ovulation tests are convenient to use at home. They can be used almost any time of the day. The test will not take long. It will only take a few minutes.

With the help of tests, the level of LH in the body can be found out quickly enough. After the test, you need to wait 10 minutes. A positive result can be seen even a little earlier.

Ovulation tests give easy-to-read results. It is only necessary to compare two strips and determine the color intensity of the test strip compared to the control line. The instructions for the Frautest ovulation tests and other similar products describe how to interpret the results of the test.

The accuracy of the tests is quite high and is 99%. This figure is confirmed by many years of clinical trials.

Ovulation tests are freely sold in Russian pharmacies. Their cost is decent, but quite affordable. One package containing 5-7 strips or cassettes will be enough for a month.

In conclusion, it is worth noting that the results of ovulation tests may be unreliable. This may be due to a defective test or incorrectly performed testing. As a result, the long-awaited moment of favorable conception may be missed. To prevent this from happening, you can combine the use of tests with other methods that allow you to determine the time of ovulation.
