What does an ovulation test mean. Can ovulation test strips test positive during pregnancy? Different tests: what will we measure

Couples planning a child often do an ovulation test - that is, to determine the most favorable time for conception. What is an ovulation test, and how to do it correctly?

How is an ovulation test done?

Monthly in female body one follicle matures - the part of the ovary in which the egg is located. At the time of maturation of the follicle, it produces female hormones estrogen. When the concentration of estrogen in the body reaches the required level, there is a sharp release luteinizing hormone (LH) which is responsible for ovulation. Within 1-2 days after the release of LH into the body of a woman, the egg is released into fallopian tube and ready to be fertilized. This phenomenon is called ovulation. And in order to find out exactly when the mature egg is released from the follicle, a special one is carried out.

This test requires samples of the woman's urine or saliva, which will then be determined for the level of the fertility hormone, luteinizing hormone (LH). This hormone is present in the body of any woman, but literally a day or two before ovulation, its concentration increases dramatically. This happens only once per cycle - when there is the greatest chance of conception. Thanks to this property of LH, on certain days of the cycle and time of day, you can do an ovulation test and find out about the most auspicious day to conceive a baby.

Ovulation test can be done at home - about the same as a pregnancy test. After all, ovulation tests are sold in ordinary pharmacies and there are several species:

- test strips . Surely, you are familiar with this type of pregnancy test - a strip of special paper soaked in a reagent. Ovulation test strips are the same strip that needs to be immersed in urine for a while, after which the result will be visible. Such ovulation tests are not very accurate and have their drawbacks.

- Test plates (or test cassettes) . Such tests also have their counterparts among pregnancy tests. The ovulation test tablet is a plastic case with a small window. It is enough to substitute this test under a stream of urine or drop a drop of urine on it - and after a few minutes look at the result in the window. Test tablets are quite reliable, however, they are more expensive.

- Inkjet tests . These are the most reliable ovulation tests currently available. Such an ovulation test is substituted under a stream of urine or lowered into a container with urine - and in just minutes you can see the result.

- Reusable ovulation tests . In fact, this is a portable device with a set of test strips. The test strips are dipped into the urine, after which they are inserted into the device - and the result can be observed very soon.

- Electronic ovulation tests . Such tests “work” not with urine, but with a woman’s saliva - you need to put a little saliva on the lens, and then either navigate using a special sensor, or look at the pattern on the saliva through the microscope that comes with the lens. What pattern means what - it is written in the instructions. Such ovulation tests are quite expensive, but they have no competitors in their reliability!

True, when deciding to do an ovulation test, it is worth remembering that all of the above tests do not show the exact timing of ovulation, but the exact timing of the release of LH into the body, shortly after which ovulation should occur. It is worth considering this when conducting such tests.

How to do the test correctly?

Unlike a pregnancy test, ovulation test is done not once, but 2 times a day for about a week. This is necessary because the peak level of luteinizing hormone concentration lasts less than 24 hours and can occur both in the morning and in the evening. In this regard, it is advisable to test for ovulation in the morning and in the evening - so as not to miss the moment when the body has the highest concentration of this hormone.

When to start ovulation testing? Doctors agree that it is necessary to start testing exactly 17 days before the expected one. For example, if your cycle is 28 days, you need to start testing from day 11 of the cycle.

Below is a table of the start of ovulation tests, depending on middle length cycle.

Testing should be carried out starting from the selected day of the cycle and until the result is positive. One significant drawback of ovulation tests is associated with this - unfortunately, they are not suitable for women with an irregular cycle.

What else do you need to know to do an ovulation test correctly?

* it is necessary to carry out tests daily and, preferably, at the same time;

* most successful period for ovulation tests is the interval from 10 am to 8 pm;

* if you are testing urine, do not use the first morning portion of urine for this purpose;

* before the procedure, pay attention to what drugs you are taking - if among them there are drugs containing luteinizing hormone, testing does not make sense;

* 1-4 hours before the ovulation test, try to consume less liquid;

* try to refrain from urinating for 3 hours before the examination.

Can ovulation tests be wrong?

In addition to the irregular cycle and the use of LH by a woman, there are several other reasons why ovulation tests may be wrong.

* Differences in the production of LH in women's bodies - for someone this hormone can be produced so intensely that even at the moments of the absence of ovulation, its level will approach sufficient for the maturation of the follicle, and for someone, even at the peak of the ability to conceive, the LH level does not reach norms;

* the error of the ovulation test itself;

* features of the woman's body (high levels of the hCG hormone, different kind diseases, etc.),

* a large number of drunk liquid shortly before the study;

* invalid testing time.

If you are with your husband, of course, you can give yourself confidence by using ovulation tests. But it is worth remembering that a test is a test, and at the same time, you should not forget about how children appear, especially since tests are sometimes wrong. Therefore, have sex not only in " right days”, but also when you both really want it! And then, for sure, soon you will have a wonderful baby!

Woman's life childbearing age greatly facilitated by special methods diagnostics. It is easy to use the ovulation test, the instruction of which fully explains how to use this method for diagnosing the moment of release of the egg.

Girls and women purchase ovulation tests only in 2 cases:

• make sure that you are “not pregnant” in case of violation menstrual cycle;
• determine the most accurate day and date when the probability of conceiving a child reaches its highest level.

The category of people who do not plan to have a baby in the near future, using this test, will be able to determine the day of ovulation and thoroughly prepare for it, that is, choose the maximum method of protection in order not to become pregnant.

Girls who want to become a mother soon will be able to identify ovulation days. This will increase their chances of conceiving a child.

The meaning of the ovulation period

The menstrual cycle is a monthly change that occurs in the life of every woman. reproductive age. This period begins on the first day of the onset of menstruation and ends on the first day of the onset of the next menstruation. normal hedgehog monthly cycle lasts approximately 21-35 calendar days, depending on the physiological features body of a particular woman. Each monthly cycle shows the girl's readiness for conception. By its nature, it goes through 3 main phases of development:

1. Follicular, which lasts about 2 weeks after the end of menstruation.
2. Ovulation. Its duration is only a few days. As a rule, a mature but unfertilized egg dies after 2 days. And already during the period of ovulation, the epithelial layer in the uterus is prepared for pregnancy. Ovulation is the period when the probability of conception is highest.
3. Luteal. If conception occurred in the ovulation phase, with the help of the hormone progesterone, the fertilized egg is introduced into the walls of the uterus. If not, there is rejection of the prepared epithelial layer, " corpus luteum" dies. Thus, the cycle ends, the next menstruation begins.

All women who wish to become pregnant should remember that conception is possible only if sexual contact occurs immediately before ovulation or within 24-36 hours after it.

What are the types of tests

You can buy an ovulation test at any pharmacy. If you have any doubts about which type and manufacturer to give preference to, you can seek help from your doctor or ask your friends. Using tests to determine pregnancy is quite simple. The mechanism of action of tests is very similar to the principle of operation of tests to determine pregnancy. Modern pharmacology offers various types of them. Basically, ovulation tests are carried out by dropping them into your own urine. In addition, some types of tests react to the composition of female saliva.

Typology of ovulation tests:

• electronic;
• test strips;
• test cassettes;
• jet.

Each of these types has its own advantages and disadvantages.

Characteristics of funds

Electronic - tests that resemble a tube of lipstick. It is they who show results under the influence of saliva. It turns out that during the ovulation period, the composition of female saliva changes - changes in the pattern of crystallization occur. To obtain a result, it is enough to place a little “reagent” on the lens and follow the data obtained for some time. How to use an ovulation test and how to decipher the result - all necessary information will be listed in the instructions for the test. Electronic tests are popular due to the reliability and accuracy of the results shown. However, their cost will be one level higher than the price of other types of tests.

Test strips. Outside and according to the principle of action, they are analogues of pregnancy tests. In order to get a result, it is enough to lower a strip of test with a reagent into a container filled with urine. Within 30 seconds you can see necessary information. The disadvantage of such tests is low level reliability. At the same time, today they are the most budget options due to the low cost.

Test cassettes. This type of test is the most convenient to use. They are also often referred to as test plates. The strip of paper on which the reagent is applied is inside the plastic case. To use the test, it is enough to put a drop of urine into a special hole or substitute plastic under a stream of urine. The result appears almost immediately. They are in high demand among women due to the good price-performance ratio. In addition, they are sold in packs, usually 5 pieces.

Inkjet. Most the new kind from all existing tests. It is believed that these tests provide the most accurate results, and are also the most highly sensitive. The result can be seen within a few minutes (usually 3-5) after exposure of urine to the reagent. Often, inkjet tests are sold in a kit with a pregnancy test. They differ from their counterparts in higher cost.

Important day calculation

• cycle duration 21-22 days - ovulation occurs on day 6;
• cycle duration 23-24 days - ovulation occurs on day 7;
• cycle duration 25 days - ovulation occurs on day 8;
• cycle duration 26 days - ovulation occurs on the 9th day.

The longer the menstrual cycle, the longer the period will be. That is, with a 27-day cycle, the ovulation period will fall on its 10th day, and so on. It is important to remember that in case of failures or irregularity of the monthly cycle, it is necessary to choose the most short period over the last 4 months. Thus, the most favorable time for conception is calculated using the folk calendar method. Constant stress, use alcoholic beverages and other factors can affect the reliability of the calendar determination of the ovulation day. advantage this method is its free. Unfortunately, the accuracy of determining the result will be low. That is why modern women they prefer to purchase a ready-made ovulation test at the pharmacy, which can more accurately predict its date.

The principle of the test

Despite significant amount varieties of tests, they all use the same mechanism that helps determine the desired date. In order to achieve the desired result, it is necessary to act exactly as the instructions for the test indicate. The functionality of the test to determine ovulation involves the presence of a number of antibodies that are able to determine the concentration of luteinizing hormone in the urine.

It should be remembered that almost all ovulation tests have the same level of sensitivity, the difference is only in the manufacturer of the product. To date, the most popular ovulation tests are Frautest, Eviplan and Solo. Which one to give preference to is a personal matter for every woman. Even one test from one manufacturer can show the reliability of the result, and there is no need to buy several packages from different pharmacological companies. The distortion of the results is possible only if there are irregular menstrual cycles. And this means that they can appear pathological processes V hormonal background women.

By determining the ovulation period, you can even plan the sex of the unborn child. It should be borne in mind that this approach is not a 100% guarantee, but it is popular among many couples. It is believed that conception on the eve of ovulation implies an increase in the chances of giving birth to a boy, and sexual contact on days distant from it contributes to the birth of a girl. How true this theory can be understood by experiencing it in practice.

Rules for the procedure

To achieve an accurate result, you should carefully study the instructions for using the test. It is always attached to its packaging.

Steps to follow when performing an ovulation test:

• fill the container (attached to the test) with urine for research;
• open the hermetically sealed packaging with the dough (you need to pay attention so that there is no damage and environmental influences);
• lower the test into a container with urine, leaving it for the time indicated in the instructions.

Regular measurement of basal temperature can increase the reliability of the information received.

In addition, it should be remembered that using an ovulation test with simultaneous reception hormones just don't make sense. This reduces the reliability of the information received. Even medicines with the content of hormonal substances used for external use (gels, ointments) can distort the result.

Before using the test to determine ovulation, it is not recommended to drink liquid in unlimited quantities (especially important in hot weather), as there is an increase in the amount of urine, as a result of which the level of luteinizing hormone concentration decreases. As a result, the test produces an incorrect result.

In the package, as a rule, manufacturers produce 5 test strips. Such a measure involves testing every 12 hours on the coming ovulation days. Thus, it is possible to most accurately determine the moment of onset of ovulation.

Subtleties in use

Instructions that come with pregnancy tests to get high score recommended to use morning urine. If we consider the mechanism, then such urine is not suitable for obtaining correct information. IN this case in order for the effectiveness to be at a high level, a woman needs to refrain from urinating for 3-4 hours.

The test result can also be distorted if the woman is already pregnant or has recently given birth to a child. Also, the premenopausal period in women can provoke an incorrect display of the data obtained.

In addition, after receiving the test results, all questions can be discussed with the attending physician.

Compliance simple rules will allow a woman to obtain reliable final data and, as a result, conceive a child in a prescribed period. It is important to note that if for several months in a row all attempts to get pregnant (with the establishment of the date of ovulation) do not bring the desired results, you should consult a doctor. Might need to go special diagnostics and examinations to establish the reason that does not allow conception.

You can conceive a child only during ovulation - during the release of the egg from the ovary. In women who have a 28-day menstrual cycle, this occurs on the 14th day, but it can happen earlier or later. Sometimes ovulation does not occur.

A woman who wants to get pregnant, using the test, determines the time of the release of the egg and the period of probable conception, planning an intimate relationship with a partner for this time.

The principle of the test is based on the registration of an increase in the level of luteinizing hormone (LH) during the release of the egg. A positive result means that the woman will be able to become pregnant within three days, and the probability of fertilization in the next 36 hours is maximum.

The test should be carried out at the same time - from 10.00 to 20.00. Urine collected in morning hours do not check. To catch highest level LH, testing is carried out twice a day. During this period, you can not drink a lot of fluids and take diuretics, and two hours before the test it is better not to drink at all. It is undesirable to test in hot weather or while taking any hormonal drugs- the result is distorted.

The principle of testing is similar to pregnancy testing, only the reagent is tuned to a different hormone.

Instructions for the test to determine ovulation

Devices for determining ovulation are available in several types:

• Strip test - a strip with a control mark, lowered for 10-15 seconds into a container with morning urine. After 10 minutes, the result is evaluated. If ovulation has occurred and the LH level has risen, a second band will appear.
• Tablet tests - plastic cases, absorbent like blotting paper. Urine is dripped into one window, and one or two stripes are visible in the other two or three minutes later.
• Jet - does not require urine collection, so it is more convenient than the previous two. It is substituted under the jet during urination. The result is visible in a minute. At elevated level luteinizing hormone, two strips will appear.
• Reusable ovulation test comprises electronic device and a set of interchangeable elements that are immersed in freshly collected urine. When using, you need to remove the device from the package, remove the cap, insert the test module until it clicks, wait for a notification that the device is ready for testing. After the dive, three minutes later, symbols will appear on the electronic screen. The circle means that ovulation did not occur and the LH level did not increase. The smiley indicates an increase in the concentration of luteinizing hormone.

In addition to tests based on urine analysis, there is a reusable system for diagnosing ovulation based on the study of saliva. This is a mini microscope that looks like a lipstick. Before ovulation or during it, a pattern similar to a fern leaf is visible on the glass. Saliva is applied in the morning on an empty stomach with the tongue or finger, avoiding the formation of bubbles. After drying, using a microscope, it is determined whether a pattern is visible on the glass by comparing it with a complete sample.

Tests produced by various manufacturers have their own characteristics, so before using, you need to carefully read the instructions for each of them.

What day after ovulation should I take the test?

The start of testing depends on the length of the menstrual cycle. As a rule, the test begins a couple of days before ovulation. More exact time indicated in the table. The duration of the intermenstrual cycle is determined by the interval between the first days of the next two periods.

If the test remains negative for five days, then the egg did not leave the ovary and the menstrual cycle was anovulatory (no ovulation).

To obtain an accurate result, the start of testing should be measured every day at the same time. basal body temperature inserting a thermometer into the rectum. Before ovulation, it fluctuates between 36.2 -36.8, and after the release of the egg, it rises to 37.1 -37.2.

Ovulation test results

At correct application tests show ovulation at 90-99%. The result is easy to read: two strips - there is ovulation, the absence of a second strip - no. Normally, during ovulation, the second strip is darker than the first. If it is too light, the LH level is low and there is no ovulation.

Ovulation test results

When using an electronic test, a smiley face lights up, and during the study of saliva, a “frost pattern” or a pattern similar to a fern leaf is visible.

Once the result is positive, no further testing should be done. You need to use these days for fertilization, and then check for pregnancy.

False positive result

• If conception has already occurred, the result is false positive. The reagent works on chorionic gonadotropin.
• An incorrect result is obtained with a metabolic disorder in a woman. The test responds to increased levels of ovarian hormones and thyroid gland showing positive result outside of ovulation. In such cases, you need to check with an endocrinologist. Sometimes the cause lies in ovarian tumors that change the hormonal background.

False negative result

• This happens when the instructions for use are violated or when expired tests are used. Sometimes a woman rushes and starts checking earlier days indicated in the table.
• The result is distorted in the presence of diseases that reduce the excretory function of the kidneys or are accompanied by edema. In this case, there is luteinizing hormone in the body, but it is not excreted in the urine. In diseases of the urinary system, it is better to use a test based on the analysis of saliva.
• It is not possible to track ovulation in women with irregular cycles, since the day of ovulation is difficult to predict.

This is interesting! With the help of an ovulation test, you can increase the likelihood of having a baby of a certain gender. X-chromosomes are slower, but "tenacious" To conceive a girl, you need to have sex a few hours after the appearance of the strip on the test, and to give birth to a boy, wait a couple of days when it becomes pronounced. The method does not give a 100% guarantee, but it works effectively.

How to choose an ovulation test

How to choose an ovulation test

The most advanced ovulation tests are inkjet. They are easy to use, and the detection accuracy is 98%. Reusable devices with replaceable strips also work well. When using, pay attention to whether the special indicator is on.

The accuracy of cheap strips is lower, and the number of false negative results when using them is higher. Use requires strict adherence to the instructions. If the strip is slightly overexposed in the urine, the result will be incorrect - the paper will get wet and the picture will become fuzzy.

The reagent included in the devices and test strips is very sensitive and deteriorates if stored incorrectly and if the deadlines are not observed. To double-check, you need to purchase a test of a different design and manufacturer. This will let you know if the results are distorted during testing. Women in many countries have long abandoned cheap tests: why conduct a study whose results cannot be trusted.

Many women feel when they are ovulating. At this time, the viscosity increases vaginal discharge, rises sex drive, pain in the ovary may be felt. However, for effective pregnancy planning, you cannot rely on these feelings. It is necessary to regularly conduct an ovulation test, which will make it possible to determine the most favorable moment for fertilization.

Why carry it out?

Ovulation is the moment when an egg ready for fertilization is released from the follicle located in the ovary into the abdominal cavity, and then into fallopian tube. Here it will unite with the sperm, resulting in the formation of a zygote. It will move to the uterus, where it will take place further development pregnancy.

In order to accurately determine the time of release of the female germ cell from the ovary and best time for conception, it is very convenient to use a special test strip. This simple study will help a couple plan their pregnancy.

Operating principle

Ovulation can be determined using a normal homemade test, which is sold in any pharmacy. The research principle is based on exact definition concentration of luteinizing hormone in the urine. The level of this substance in women varies depending on the period of the menstrual cycle. Just before ovulation, it reaches its maximum values.

The ovulation test makes it possible to register such an increase in the level of luteinizing hormone, the peak of which will indicate the onset of ovulation. It works on the same principle as a pregnancy test. It uses other substances that respond to an increase in the concentration of luteinizing hormone, and not human chorionic gonadotropin.

On sale there are devices for determining luteinizing hormone in saliva. They are more convenient, designed for repeated use, but have a high price.

positive test ovulation indicates that the most best moment for the conception of the future baby falls on the next 2 days.

Some women use such testing to determine " dangerous days" at calendar method pregnancy protection. However, the effectiveness of this method is low. Spermatozoa that have entered the genitals of a woman can linger in them, "waiting" for the release of the egg. Therefore, it is possible to become pregnant with sexual contact that occurred before the release of the egg.

Rules for holding

Most tests contain 5 strips. This is due to the fact that it is extremely rare to calculate the moment of ovulation at once, and repeated studies significantly increase the accuracy of diagnosis.

What day is the right time to do an ovulation test?

You need to start testing on the eve of the expected date of release of the egg. It is necessary to determine the duration of the menstrual cycle and subtract 17 days. If the cycle lasts 28 days, you need to start the study from day 11, counting from the first day of menstruation. At irregular periods as a basis, you need to take the average value of 4 or even 6 cycles in a row.

How to use an ovulation test?

Each box contains detailed instructions. You just need to place the test strip in a container of warm urine or substitute it under the stream when urinating, and then dry and save. The next strip is used in exactly the same way at the same time. This is repeated until a positive result is obtained.

• within 4 hours do not drink water and other liquids;
• do not urinate at least 2 hours before testing;
• do not use the first portion of urine obtained in the morning;
• the best time for testing is from 10 am to 8 pm.

Ovulation test results

After completing the study, a woman can get the following indicators:

• absence or very weak line (significantly paler than the control) - the test is negative;
• there are both strips, not counting the control - the test is positive.

If the test is negative, it means that it will take some time before the egg is released.

If the test showed two stripes, this indicates a possible release of the egg from the follicle within the next 12-48 hours. The brighter the second strip appears, the greater the concentration of luteinizing hormone, and the closer ovulation. A positive result persists for 1-2 days, rarely for 3 days.

If none of the strips is visible, this is a sign that the test is not suitable for use.

A positive test confirms the highest fertility during the menstrual cycle. If a woman is trying to get pregnant, she needs to plan sexual intercourse within the next 3 days after ovulation.

False test results

It may happen that the test result is positive, but ovulation does not occur. Substances that react to the concentration of luteinizing hormone in the urine are very sensitive. Therefore, there is a slight chance that they will catch a small increase in the concentration of the hormone.

Most effective method confirm ovulation - ultrasonography ovary. Many women measure at the same time as testing. This is a simple and informative way to find out at home about the onset of ovulation. The temperature in the rectum rises the next day after this. Combined with testing, this gives an accurate result.

Sometimes, despite negative result ovulation still occurs. This is usually due to non-compliance with the instructions for using the test. The study should be carried out at the same time, in the afternoon or in the evening. In addition, an irregular cycle may be the cause, and then other methods are used to determine the time of release of the egg.

Contraindications for use

The results can be distorted under the influence of hormonal drugs prescribed to a woman about gynecological diseases( , and others). However, these drugs in most cases also have a contraceptive effect, so getting pregnant while taking them will not work.

Ovulation tests are not performed during pregnancy or after menopause.

Best Ovulation Tests

In pharmacies, you can buy test kits from different companies. Let's consider some of them.

digital test for ovulation Clearblue

Shows results with 99% accuracy. It consists of a plastic case and a test module. Before starting the study, you need to remove both parts of the test and insert the strip into the case until it clicks. Then you need to wait for the flashing symbol to appear on the body of the device. It will show that the test is ready to use.

Ovulation test "Clearblue"

Next, you need to collect a portion of urine in a dry, clean container and place the absorbent part of the strip in it for 15 seconds. You can simply put the end of the test module under the stream while urinating for 5 seconds, but there is a danger of wetting the device itself.

The body can be placed on flat surface or hold the sampler down. You can not lift it with a strip up. After half a minute, a flashing signal will appear, indicating that the result is ready. After that, you need to remove the test, remove the cap from it and wait 3 minutes.

After this time, a “smiley” will appear on the body of the device. This means that ovulation has come, and the best time to conceive is the next 48 hours. If the circle remains empty, then the hormone level is normal. After that, you need to throw away the strip, and the next day, repeat the study.

No need to pay attention to the stripes that appear on the test module. You can find out the result only on the display of the device. It is displayed for 8 minutes.

The digital ovulation test is highly accurate. When using it, you do not need to independently evaluate the brightness of the strips. This makes Clearblue one of the best products in its segment. It is more expensive than conventional strips, but it is more convenient to use and more reliable.

Frautest for ovulation

If a woman has a reason to use not electronic device, and test strips, Frautest is suitable for her. The kit contains 5 strips for determining luteinizing hormone, as well as 2 tests for diagnosing pregnancy. In addition, there are 7 containers for urine, which increases the convenience of use.

After 5 seconds, you need to remove the strip and put it to dry on the edge of the container with urine. Colored lines will start to appear after a minute, but the final assessment is made after 10 minutes. If 2 bright lines appear, the test is positive. It is not recommended to evaluate the result after 30 minutes or more.

The test is one-time, after use it and the urine container must be thrown away.

Other popular test strips are Eviplan, Ovuplan, Femiplan.

Tablet tests

Devices that combine ease of use and accuracy - tablet, or cassette.

Tablet (cassette, inkjet) test for ovulation "Femitest"

These are reusable devices that determine ovulation in the urine. It is enough to substitute the window of the device under the jet, and after a while one or two strips will be displayed on the screen. Examples of such tests are Frautest, Evitest, Ovuplan Lux, Femitest cassettes.

Electronic test that determines the level of estrogen in saliva

Considered the most reliable. Hence its high cost. The principle of its work is to study a drop of saliva under a microscope. Before ovulation, salt crystals begin to form in it, first forming horizontal and vertical lines, and at the time of ovulation, a pattern resembling a fern. If ovulation has not occurred, the saliva sample contains only individual grains - “sand”.

The readings of this test do not depend on the level of luteinizing hormone. Therefore, it is especially suitable for women with hormonal disorders.

The simplest device in the series is the MaybeMom microscope. It is equipped with good optics and gives a reliable result in 98% of cases. The OVU test allows you to examine not only saliva, but also cervical mucus. Eva-Test is a mini-laboratory, fully computerized and independently issuing ready-made data on ovulation.

Test microscope "Maybe Mom" ​​for determining ovulation by a drop of saliva

Electronic tests that determine ovulation by saliva are considered the most accurate. Compact microscopes are easy to use and convenient. They are reusable, there is no need to constantly buy test strips. You need to examine saliva in the morning, before drinking water and brushing your teeth.

Some devices, such as Eva-Test, make it possible not only to determine ovulation, but also to protect yourself from pregnancy, to notice the threat of miscarriage in time. Such an ovulation test shows pregnancy for a period of 1 week. It is able to help in the diagnosis of gynecological diseases and even determine the sex of the unborn baby. Although consumer reviews speak of some inconvenience of the device, the need to reconfigure it and the high price, for some women it is best suited.

The Vesta device also belongs to this category. Manufacturers claim that such devices also show “safe” days, hormone levels in menopause, possible cause absence of menstruation.

FAQ

What is the chance of pregnancy on fertile days?

The chance of getting pregnant will vary from cycle to cycle, and different women. It depends on many conditions such as the age of the woman, her partner, general state health and lifestyle. On average, the probability of pregnancy on the day of ovulation is 33%.

What is the difference between using most ovulation tests and the Clearblue Fertility Monitor?

Most ovulation tests detect the release of luteinizing hormone, which occurs about 24-36 hours before the release of the egg. They help clarify the 2 most fertile days of the cycle - before ovulation and during this process. The Clearblue Fertility Monitor digital test determines the level of two hormones - luteinizing and estrogen. It reveals up to 5 extra days when a woman can become pregnant by detecting a rise in estrogen.

I recently stopped taking birth control pills. Could this change the result?

No, this will not affect the results. But if a woman has only recently stopped taking hormonal agents, she may have irregular cycles. This leads to difficulties in determining the day of testing. Therefore, it is better to wait until 2 consecutive cycles without contraceptives have passed, and only then start using ovulation tests.

My cycle is outside the range shown in the instructions. How do I know when to start testing? When to test for late ovulation?

If the cycle is less than 22 days, you need to start testing on the 5th day, counting the first day of menstruation. If the cycle is more than 40 days, you should start testing 17 days before the expected start of menstruation and continue testing even after 5 days.

I enjoyed clearblue test several months in a row and did not get pregnant. Maybe I'm infertile?

I did all 5 tests according to the instructions, but did not detect ovulation. What to do?

If the length of the cycle changes monthly by more than 3 days, you need to start new packaging test. If the cycle is normal, then it was neoovulatory, that is, there was no release of the egg. It will no longer be possible to get pregnant this month, but this normal phenomenon for the female body.

Do I need to use all the tests in the suite?

No. It is possible to stop testing after ovulation and save the remaining strips for the next cycle.

I did the test incorrectly, what should I do next?

The best solution is to conduct another study on the same day 4 hours after the failed one. At this time, you need to drink less and not urinate. If the urine was collected in a plastic container, you just need to take another strip and analyze it right away.

When are the chances of getting pregnant the highest and lowest?

The peak of the possibility of conception occurs on the day of ovulation and the day before it. High probability pregnancy appears 4 days before. Outside of these 6-7 days, the chance of getting pregnant is low.

What is the difference between ovulation days and "fertile" days?

Ovulation is the release of the female germ cell from the follicle, this happens 12 to 16 days before the start of the next menstruation. A woman is most fertile on the day of ovulation and on the previous day.

"Fertile" days - the time of the cycle when pregnancy can occur. Due to the fact that spermatozoa remain in the female body for several days, they can “wait” for an egg. Therefore, “fertile” days are considered the day of ovulation and 5 days before it.

Instruction

There are several types of ovulation tests. The most common of these are paper test strips that are lowered into a vessel with urine, the result is shown in them by the development of two multi-colored lines. Slightly more advanced are available in the form of plastic cassettes, urine is applied to the test area with a pipette. And the most advanced are mini-computers that display the result of the test on the display. But they all work on the same principle - a special substance reacts with the luteinizing hormone and allows you to evaluate its concentration in the urine.

A mature egg is capable of fertilization for only a very short time. This period is only a day after ovulation. Modern tests make it possible to track this moment with fairly high accuracy, since luteinizing hormone becomes the very substance that provokes the release of an egg from the ovary into abdominal cavity, and it is its presence that the test reagent shows. The highest concentration is observed in the body exactly 24 hours before ovulation. And if within a day after the test has become positive, a woman has sexual intercourse, her chance increases significantly.

Correct use tests for can be considered at their simplest version. Usually one package contains 5 test strips and should be started 5-6 days before the expected ovulation. Having collected a portion of morning urine, it will be enough to lower the strip into it to the designated line, put it on a flat surface and wait for the test readings. It should be remembered that the appearance of the second strip cannot be unambiguously interpreted as a positive result. Luteinizing hormone is also found in the urine a few days before ovulation, so a weak line on the test will mean absolutely nothing, and only when the test and control strips are the same color, it will be possible to say with confidence that there are only a few hours left before the release of the egg from the ovary .

note

A positive ovulation test does not mean a guaranteed pregnancy in this cycle. The likelihood of conception depends on many factors, and some women take several months before they can be congratulated on this wonderful event.

Helpful advice

The results of ovulation test cassettes are evaluated in the same way as test strips. But the computer itself state will determine whether the concentration of the hormone is sufficient to declare the result positive.

The need to determine favorable days for conception is faced by women planning a pregnancy. Among the many ways to find out the day of ovulation, homemade tests are particularly popular. The reason for this is the simplicity of the study and the accuracy of the results.

Instruction

Buy tests for ovulation available at any pharmacy. Despite the range and number of varieties, their action is reduced to determining the level of luteinizing hormone in the urine. Its sharp release is noted during the period of ovulation, and tests for this give a positive result.

It takes more than one day for the egg to mature. This process is individual for each. Someone happens on the tenth, and someone is forced to wait for her for months. With a standard of 28 days, it matures by the fourteenth day from the onset of menstruation. If the cycle is longer or shorter lunar month, the day of ovulation is impossible to guess.
