An ovulation strip test is the easiest and most accurate way to find out exactly those days when the likelihood of conceiving a child is maximum. Therefore, women who cannot get pregnant enough for a long time, or are carefully planning the birth of a baby, it is recommended to carry out special tests that make it possible to determine ovulation almost certainly. How to do such studies, how to choose the right time for testing, how to interpret the results, read below.
When the chance of pregnancy is high
Around the middle of the menstrual cycle, the body begins to actively synthesize a special hormone, LH (luteinizing hormone), which “triggers ovulation,” that is, leads to the rupture of the follicle with the egg. And if the egg meets the sperm within the next 1-2 days, fertilization will occur and pregnancy will occur. But since after leaving the ovary the cell lives only (approximately) a day, it is very important to determine the time of ovulation so that conception occurs for sure. This can be helped by special tests that are freely sold in pharmacies. Typically the package contains 5 ovulation test strips, 2 pregnancy test strips, and urine collection containers.
When to do an ovulation test
The basis of such a study is to check the content of the LH hormone in the body. The tests are simple: just collect a portion of urine, but not in the morning (as for a pregnancy test), but in the middle of the day or in the evening. Then you should immerse the test in it and wait for the result to appear: the likelihood of conception is greatest if you see two bright stripes of the ovulation test. If there is only one, continue research for a few more days. In order to accurately calculate the time for such studies, you need to subtract 17 from the number of days of the cycle. For example, if your menstrual cycle is 29 days, then testing should begin on the 12th (29-17 = 12). If your periods come irregularly, then it is recommended to take the minimum duration of your cycle as the number of days.
How to read results
So, having timed the research, you need to correctly interpret (read) its results. For example, if an ovulation test showed two lines, then conception is possible - with sexual intercourse within 48 hours after receiving this result. In this case, the probability of pregnancy is very high. Modern tests very sensitive, their reliability is up to 99%. Therefore, one strip of the test shows that the egg has not yet left the ovaries, that is, the LH hormone accompanying the process is absent in the urine. A pale line on an ovulation test indicates that the LH surge is sufficient quantity has not yet occurred, in this case you need to continue testing until the second strip becomes as bright as the first, control one. Typically, the maximum concentration of the hormone in the urine is detected within 48 hours (it is at this time that the egg moves through the fallopian tube and is ready to meet the sperm), that is, the question of how many days an ovulation test shows 2 stripes can be answered - approximately 2 day. It is during these two days that the probability of conception is maximum.
Please note that the test does not always give the correct result. It may be affected by certain hormonal medications taken, the presence of a number of diseases associated with ovarian dysfunction, as well as renal failure etc. Nutrition plays a significant role in this issue, for example, if your food is rich in phytoestrogens, or there has been a sharp transition to vegetarian diet or raw food diet, test results may be false positive. Take these factors into account when conducting research and, if necessary, consult with a gynecologist who can prescribe an ultrasound (folliculometry) for the most accurate determination of ovulation.
Ovulation is a stage of the menstrual cycle necessary for conception, during which a mature follicle ruptures and an egg ready for fertilization is released into the abdominal cavity from the uterus. If conception does not occur within 36-48 hours from the beginning of the peak of ovulation, then the egg will die in the fallopian tube in the next 24 hours.
In nature, everything happens by itself, but for modern woman everything is much more complicated. Increased pace of life, constant busyness and health problems often cause failure reproductive system. So you have to adapt to The biological clock, calculate the most suitable time for fertilization.
A great way to determine the time of peak ovulation– use special tests. Smart strips react to a sharp increase in the content of luteinizing hormone in a woman’s urine. Maximum magnification The indicator is observed 24-36 hours before ovulation itself - this time is the most acceptable moment for conception.
The right approach guarantees results
Depending on the length of your menstrual cycle, it will be determined when to take an ovulation test. The cycle itself will be equal to the number of days that have passed from the first day of the previous menstruation to the first day of the next. The situation is complicated by the fact that not all women have a stable cycle.
It is easier to decide with a constant cycle; in this case, the time to act comes approximately seventeen days before the new expected cycle, i.e. before the first day of the next menstruation. This time is called phase corpus luteum and lasts, on average, up to 16 days.
If the cycle is stable, equal to the standard 28 days, home tests should be started from the eleventh day. The calculation is simple - you need to subtract 17 days from the number of days in the cycle. If, for example, the cycle is stable, but it is longer and equal to 34 days, then testing will also be later - starting from the seventeenth day.
Otherwise, the start time of using the test is determined for different cycle durations. In this situation, you need to identify the shortest cycle over the last six months; this cycle will be taken into account to determine the day when you should start testing for ovulation.
If the instability of the cycle is alarming and delays can reach a month or more, then it would be more rational to think about additional control over ovulation, as well as over the follicles. Using tests alone in this case can be unreasonably expensive, and due to the length of the cycle, it is easy to miss hour X.
Home procedure: minimum time and maximum guarantees
Doing tests to determine ovulation at home is extremely convenient and simple. All questions that arise regarding how to do an ovulation test will be answered by the instructions included with the test, and in the event of a menstrual cycle failure, consultation with a female specialist will be necessary. This procedure replaces ultrasonography, but you don’t have to go anywhere for this, everything is done in a comfortable home environment. In addition, going for an ultrasound scan for several days is not cheap, and is questionable in terms of health safety.
Tests are used daily, and in some cases even twice a day - in the morning and in the evening. If control is carried out not only with the help of tests, but an ultrasound is done to guarantee, then you can save on tests by skipping those days when the follicle has not yet acquired right size for ovulation. But when it increases to 18 mm, testing should be carried out consistently every day, then a good result will definitely be achieved.
How to do an ovulation test correctly?
Doubts about how an ovulation test is done and whether it is done correctly are in vain if everything is calculated correctly for the cycle and the instructions are followed. The main thing is to conduct testing at approximately the same time of day, which will facilitate a more accurate comparison of information.
The appropriate time is determined by the woman herself, when it is most convenient for her to carry out the procedure. But in order to do the test, you need to fill bladder Therefore, if possible, you should avoid urinating for at least four hours. However, the accumulation must be natural, the liquid must be consumed in moderation so as not to distort the indicators of luteinizing hormone, which will negatively affect the reliability of the result.
The procedure itself is carried out as follows. You need to collect an average portion of urine in a clean jar and lower the test strip into it for five seconds to the line indicated on it. Next, the test is placed on a dry and clean surface, for example, on Blank sheet paper. The result can be assessed after 10-20 seconds. When using test devices instead of strips, the procedure is performed slightly differently.
Many women feel when they are ovulating. At this time the viscosity increases vaginal discharge, libido increases, pain may be felt in the ovary area. However for effective planning During pregnancy, you cannot rely on these sensations. 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 occur further development pregnancy.
In order to accurately determine the time of release of the female reproductive 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 a pregnancy.
Operating principle
Ovulation can be determined using the usual home test, which is sold in any pharmacy. The principle of the study is based on the accurate determination of the concentration of luteinizing hormone in the urine. The level of this substance in women fluctuates depending on the period of the menstrual cycle. Immediately before ovulation it reaches its maximum values.
An 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 increased concentrations of luteinizing hormone, rather than human chorionic gonadotropin.
There are commercially available devices for determining luteinizing hormone in saliva. They are more convenient, designed for repeated use, but are more expensive.
A positive ovulation test indicates that the best moment to conceive a future baby is in the next 2 days.
Some women use this testing to determine " dangerous days" at calendar method protection from pregnancy. However, the effectiveness of this method is low. Sperm that enter the woman’s genitals can linger there, “waiting” for the release of the egg. Therefore, you can get pregnant even if you have sexual intercourse before the egg is released.
Rules
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 take an ovulation test?
Testing should begin on the eve of the expected release date of the egg. It is necessary to determine the duration of the menstrual cycle and subtract 17 days. If the cycle lasts 28 days, the study should begin on the 11th day, counting from the first day of menstruation. At irregular menstruation You need to take the average value of 4 or even 6 cycles in a row as a basis.
How to use a test to determine ovulation?
Each box contains detailed instructions. All you need to do is place the test strip in a container with warm urine or place it under the stream when urinating, then dry and store. The next strip is used in exactly the same way at the same time. This is repeated until they receive positive result.
- do not drink water or other liquids for 4 hours;
- do not urinate at least 2 hours before testing;
- do not use the first portion of urine received in the morning;
- The best time for testing is from 10 a.m. to 8 p.m.
Ovulation test results
After completing the study, a woman can get the following indicators:
- absence or very weak line (much paler than the control line) – the test is negative;
- There are both strips, not counting the control one - the test is positive.
If the test is negative, it means it will still be some time before the egg is released.
If the test shows two stripes, this indicates the possible release of the egg from the follicle within the next 12-48 hours. The brighter the second stripe appears, the greater the concentration of luteinizing hormone, and the closer ovulation is. A positive result lasts 1-2 days, rarely for 3 days.
If none of the stripes are visible, this is a sign that the test is unusable.
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 detect a slight increase in the concentration of the hormone.
Most effective method confirm ovulation - ultrasound examination of the 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 a negative result, ovulation still occurs. This is usually due to failure to follow the instructions for using the test. The study should be carried out at the same time, during the day or evening. In addition, the cause may be an irregular cycle, and then other methods are used to determine the time of release of the egg.
Contraindications for use
Results may be distorted by hormonal drugs prescribed to a woman for gynecological diseases( , and others). However, in most cases these drugs also have contraceptive effect, so you won’t be able to get pregnant while taking them.
Ovulation tests are not performed during pregnancy or after menopause.
The best ovulation tests
Test kits from various companies can be purchased at pharmacies. Let's look at some of them.
Clearblue digital ovulation test
Shows the result with 99% accuracy. It consists of a plastic case and a test module. Before starting the test, you need to remove both parts of the test and insert the strip into the body until it clicks. Then you need to wait for the flashing symbol to appear on the device body. It will indicate that the test is ready to use.
Clearblue Ovulation Test
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 place the end of the test module under the stream when urinating for 5 seconds, but there is a danger of getting the device itself wet.
The body can be placed on a flat surface or held with the sampler facing down. You can't lift it upside down. After half a minute, a flashing signal will appear indicating that the result is ready. After this, you need to take out the test, remove the cap from it and wait 3 minutes.
After this time, a “smiley” will appear on the device body. This means that ovulation has occurred, and the best time to conceive is the next 48 hours. If the circle remains empty, it means the hormone level is normal. After this, you need to throw away the strip and repeat the test the next day.
There is no need to pay attention to the stripes that appear on the test module. You can find out the result only on the device display. It displays for 8 minutes.
Digital ovulation test has high accuracy. When using it, you do not need to independently evaluate the brightness of the stripes. This makes Clearblue one of best products in its segment. It costs more than regular strips, but it is more convenient to use and more reliable.
Frautest for ovulation
If a woman has a reason to use test strips rather than an electronic device, 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 urine containers, which increases ease of use.
Test strips for determining ovulation "Frautest"
The strip should be immersed in the container with urine in the direction of the arrows to the Max mark; there is no need to immerse it deeper. After 5 seconds, you need to take out the strip and place it on the edge of the container with urine to dry. Colored lines will begin to appear within a minute, but final assessment is made after 10 minutes. If 2 bright stripes appear, the test is positive. It is not recommended to evaluate the result after 30 minutes or more.
The test is a one-time use; 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) ovulation test “Femitest”
These are reusable devices that detect ovulation in urine. It is enough to place the device window under the stream, and after a while one or two stripes will appear 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 his high price. The principle of its operation is to examine 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 moment 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 are independent of luteinizing hormone levels. Therefore, it is especially suitable for women with hormonal imbalances.
The simplest device in the series is the MaybeMom microscope. It is equipped with good optics and gives 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 producing ready-made ovulation data.
Test microscope “Maybe Mom” for determining ovulation by a drop of saliva
Electronic tests that determine ovulation using saliva are considered the most accurate. Compact microscopes are easy to use and convenient. They are reusable, so 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 against pregnancy and to notice the threat of miscarriage in time. This ovulation test shows pregnancy at 1 week of pregnancy. It can help in diagnosing gynecological diseases and even determine the sex of the unborn baby. Although consumer reviews indicate 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 during menopause, possible reason lack of menstruation.
FAQ
What is the probability of pregnancy on fertile days?
Your ability to get 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 measure the release of luteinizing hormone, which occurs approximately 24 to 36 hours before the egg is released. 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 hormone and estrogen. It reveals up to 5 extra days, when a woman may become pregnant while detecting a rise in estrogen.
I recently stopped taking birth control pills. Could this change the outcome?
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 start date of testing. Therefore, it is better to wait until 2 consecutive cycles have passed without contraceptives, 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, testing should begin on the 5th day, counting the first day of menstruation. If the cycle is more than 40 days, testing should begin 17 days before the expected start of menstruation and continue testing even after 5 days.
I used clearblue test several months in a row and did not get pregnant. Maybe I'm infertile?
It happens that healthy woman unable to get pregnant for many months. A doctor should be consulted after a year of unsuccessful attempts if the woman is under 35 years old. If she is 35-40 years old, this needs to be done in six months. If a patient over 40 years of age has never taken contraception and has not become pregnant, she urgently needs to go to a gynecologist.
I did all 5 tests according to the instructions, but still did not detect ovulation. What to do?
If your cycle length changes by more than 3 days monthly, you need to start new packaging test. If the cycle is normal, it means that it was non-ovulatory, that is, there was no release of an egg. It will no longer be possible to get pregnant this month, but this is normal for female body.
Do I need to use all the tests in the set?
No. You can stop testing after ovulation and save the remaining strips for your next cycle.
I did the test incorrectly, what should I do next?
The best solution is to conduct another test on the same day, 4 hours after the failed one. During 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 carry out the analysis immediately.
When are your chances of getting pregnant highest and lowest?
The peak possibility of conception occurs on the day of ovulation and the day before it. A high probability of pregnancy appears 4 days before. Outside of these 6-7 days, the possibility of getting pregnant is low.
What is the difference between ovulation days and “fertile” days?
Ovulation is the release of the female reproductive cell from the follicle; this happens 12–16 days before the start of the next period. A woman is most capable of conceiving on the day of ovulation and on the previous day.
“Fertile” days are the time of the cycle when pregnancy can occur. Due to the fact that sperm remain in the female body for several days, they can “wait” for the egg. Therefore, “fertile” days are considered the day of ovulation and 5 days before it.
A home ovulation test is the most convenient and reliable way to determine the approach of the most auspicious days for conception. This information will be useful when planning a pregnancy or, conversely, will be a signal for special vigilance for those taking contraception. A gynecologist may also recommend an ovulation test to obtain additional data when diagnosing female problems.
Ovulation tests are designed to give a reaction to increased amount luteinizing hormone in urine. Luteinizing hormone (LH) in women is responsible for normal work gonads and, in particular, for ovulation. Increased production of LH in the female body is a sure sign of approaching ovulation. Thus, ovulation after positive test should occur in 1-2 days.
Difficulty of definition exact day ovulation lies in the fact that LH is elevated for several days. That is, two lines on an ovulation test can appear two days before ovulation and the day after it. To achieve an accurate result, you need to approach this matter very thoroughly and responsibly. You will probably have to do several tests, which, fortunately, the manufacturers take into account - the package usually contains a set of 5-7 test strips.
When to do an ovulation test: calculating the timing
The most important thing is to figure out when to take an ovulation test in your specific case. First, you need to determine the average duration of your menstrual cycle - the number of days from the start of your period until the next one. If the body is “like a clock,” then testing can begin 17 days before the start of the next menstruation. That is, with a constant cycle of 28 days, the first test is done on its 11th day.
If the interval between menstruation fluctuates by several days, then you should take the shortest cycle over the last six months as a basis, and base your calculations on this figure. In this case, your research may take a little longer, but the risk of missing ovulation is significantly reduced. In the case of an unpredictable cycle, frequent and long delays“calculating” ovulation on your own is simply ineffective - such a waste of money, time and nerves may not bring any results at all. It's better to contact medical institution, where the maturation of follicles can be monitored using ultrasound.
Optimal testing conditions
Unlike pregnancy tests, it is not advisable to use morning urine to determine LH levels. The period when it is most advisable to do an ovulation test is from 10 a.m. to 8 p.m. It is better to use this interval twice, testing in the morning and in the evening, since LH levels can change significantly even within one day.
Drinking alcohol does not affect the test results, but smoking is one of the factors due to which the level of this hormone in the body may be reduced. Other common causes of low LH include obesity, stress, and medicines. An increase in LH in the body can again be caused by stress, exhaustion due to malnutrition, or physical activity, kidney failure. In addition, the level of this hormone can be affected by endocrine disorders and illness.
Evaluation of test results
The fact that the result is positive is indicated by two lines on the ovulation test. However, it is important that the result strip is the same as the control one, or even brighter. If the result line is less pronounced than the control line, then the recorded LH level does not correspond to the desired maximum level. The presence of only one, distant line is a negative result. In the last two cases, you need to continue doing tests until you get two clear stripes.
Ovulation after a positive test occurs approximately 24-48 hours later - this period is the most fruitful in the birth of a new life. It is important to take into account that if a positive result was obtained immediately, on the first attempt, then there is a possibility that ovulation has already occurred. It is also possible that after obtaining a faint band in the first test, further attempts failed to show a decisive two bands. Most likely, the period was not chosen very well, and ovulation has already passed - the test showed only “residues” of LH after its maximum surge.
Next time, start testing a few days earlier, eliminating as much as possible the possibility of influence of factors that lead to a decrease in the amount of LH in the body. For greater accuracy, you can also arm yourself with a measurement basal temperature How additional method determination of ovulation.
Pregnancy test after ovulation
Since such studies are used primarily to increase the likelihood of conception, the question of how soon after ovulation to take a pregnancy test is very relevant. You will have to overcome impatience, since there is no point in rushing through checks. Even if conception occurred during the period you recorded, determine this using home rapid test It will be possible in about two weeks. 4.6 out of 5 (29 votes)
After all, there are special tests for this. However, not everyone knows how to do an ovulation test.
Today it is not difficult to determine, because there are special tests for this. However, not everyone knows how to do an ovulation test.
As you know, without ovulation, conception is impossible, and therefore knowing when it occurs is very important. Every person must approach the issue of procreation responsibly. Pregnancy planning is a primary and extremely important process. However, not in every case, conception occurs immediately as soon as the family decides to have a child. Some couples have to wait a long time. This is often due to health problems of one of the partners, but in some cases the cause is an incorrectly calculated time of ovulation.
If you don’t know exactly when in a woman’s body the egg will become ready and the sperm will be waiting, you can try to conceive a child for a long time. In a month, or more precisely in one menstrual cycle, nature has allocated only a few days to get pregnant, so favorable time should be determined in advance.
Every woman who is going to become a mother should know what ovulation is. This natural process for a healthy female body, without which it is impossible to conceive a baby. Ovulation occurs once a month, but the periodic absence of a mature egg in the menstrual cycle cannot be ruled out. This can happen about twice a year. Rare is acceptable and is not considered a pathology. In young girls this is practically impossible, but as women age, they may encounter a similar phenomenon.
At its core, ovulation is one of the stages of the menstrual cycle, during which the follicle develops, and then the egg enters the fallopian tube for its further fertilization with male seminal fluid. The duration of ovulation directly depends on how long the mature egg will live. If during this time she is not fertilized, she will die. As a rule, this occurs 20-40 hours after the cell enters the fallopian tubes.
In nature, no one pays attention to such a process as ovulation. Everything happens by itself. However, for a modern woman, this process can play an important role when planning a pregnancy. A complex life rhythm, an endless lack of time and catastrophic employment can lead to a malfunction in the functioning of the reproductive system. For this reason, the fair sex often has to rely on the biological clock and look for the most favorable periods for conception.
The best diagnostic methods
Considering how responsibly many couples take pregnancy planning, they have created various ways to determine ovulation. One of the most convenient and effective is the test.
In modern pharmacies you can purchase ovulation tests in various options. They differ in both price and quality. The sensitivity of the tests may vary, but the principle of operation is practically no different. The effect of pharmaceutical products for determining ovulation is based on the amount of luteinizing hormone, which is sometimes simply called LH. In most cases, determining its level at home occurs by testing urine. Maximum concentration LH in a woman’s urine is achieved approximately one day before ovulation. The time from this moment is considered the most favorable for conception.
In addition to pharmaceutical products, they often use traditional methods. They are based on the length of the menstrual cycle, as well as changes in basal temperature and other factors. For example, some representatives of the fair sex are so sensitive that they are able to independently determine the period of ovulation. The maturation of the egg is accompanied by increased secretions, increased sexual desire and unpleasant sensations lower abdomen.
To more accurately determine the period of ovulation, you can contact a specialist. IN in this case An ultrasound examination is performed. The disadvantage of this method of determining ovulation is that the ultrasound procedure is not cheap, and one session will not be enough. The exact results become known around the second or third visit to the doctor.
Menstrual cycle
And yet, in our time, they are the most popular. They are very easy to use and give accurate results. It is important to know how to use an ovulation test correctly so as not to miss a favorable moment.
It is believed that ovulation should occur in the middle of the cycle, if the first day is taken as its beginning critical days. Therefore, in order to determine when to do an ovulation test, you need to focus on the woman’s menstrual cycle. If a woman’s menstrual cycle lasts 28 days, then the maturation of the egg should occur on the 14th day. In this case, you can do an ovulation test for the first time at 11-12 days.
If a woman’s menstrual cycle is normal and stable, then there should be no problems. It will be much more difficult for those whose cycle shifts in one direction or the other.
Many experts recommend calculating time according to the 17-day rule. In this case, exactly 17 days are subtracted from the menstrual cycle and the test is used at this time. In other words, if the cycle lasts 28 days, then it is better to start testing urine on the 11th day, that is, approximately 6-8 days after menstruation, and if, for example, the cycle lasts 32 days, then on the 15th day.
If menstrual cycles V Lately were not stable, it is worth choosing the shortest period over the last six months. Next, the start date for using the tests is determined from standard calculations.
With significant instability of the cycle, which is accompanied by frequent delay critical days, you should seek help from a specialist. Here you cannot do without additional control over ovulation. Otherwise, you might miss the most favorable period for conception.
Rules for using tests
It is not difficult for a woman to determine her ovulation period at home. Modern pharmaceutical products very easy to use, and any questions can be answered by the information in the included instructions.
Qualitative tests can produce very accurate results. Sometimes they are not inferior to ultrasound examination. However, in the case of the test, everything is much more convenient and profitable.
Sometimes, for greater guarantee, a woman first goes for an ultrasound, and only after that she relies on the test results. It would be advisable to start testing if the ultrasound examination showed that the follicle size is about 18 millimeters. From this moment you can start using pharmaceutical products. With the right approach, a good result will be guaranteed.
The procedure for testing urine for LH at home is very simple. All questions that a woman may have are described in the instructions. To make the information more accurate, it is worth using the tests at approximately the same time every day.
The woman chooses what time of day to conduct the test herself, taking into account her daily schedule. However, it is worth remembering that urine is required for testing. It is not recommended to go to the toilet 4 hours before this process. The accumulation of fluid in the body must occur naturally. You should not drink a lot of water during this period so that the test can accurately determine the amount of luteinizing hormone.
To carry out the procedure for determining ovulation in the body, you need to collect a small amount of urine in a clean jar. Then the test strip is lowered into the liquid to the mark indicated on it.
The test must then be transferred to a clean, dry surface. A regular piece of paper will do just fine. Modern pharmaceutical means for determining ovulation act very quickly. As a rule, the exact result can be seen within 15 seconds.
Nowadays you can buy in pharmacies various means to determine the period of ovulation. The most common tests are in the form of strips and special devices. As for the latter, their use is somewhat different from the first option.
In this case, there is no need to use containers to collect urine, since the tip of the test can simply be placed under the stream. If this seems inconvenient, you can still collect the liquid in a jar and dip the tip of the dough into it. In any case, the test must be held in a downward direction. After about 20 seconds, the cap is put on the device. The test results can be seen in 2-3 minutes.
If the test shows only one line, it means there is no ovulation yet, and the procedure is done again in a day. When two stripes appear, the level of luteinizing hormone reaches the required level, which indicates a favorable time for conception.
Getting the result
If the test was used correctly, the result will be one of three options. A clear sign ovulation are 2 clear and bright stripes on the test. In this case, the couple needs to act in the next 20-30 hours.
If the second line on the test is weakly expressed, you must wait a little longer, since in this case there is no talk of ovulation in the coming days. You need to wait and try to repeat the test the next day.
It is also possible that there is simply no second line on the test. This is not a reason to think that ovulation has not occurred. Here we are talking rather about the unsuitability of the test, which needs to be replaced by another, better one.
Could there be mistakes?
As a rule, ovulation tests give fairly accurate results, however, errors cannot be ruled out. For a number of reasons, pharmaceutical products for determining egg maturation may give incorrect results.
This primarily applies to those women whose hormone production is excessive. In this case, even in the absence of ovulation, the test will show a positive result.
In some women, the body may produce too little luteinizing hormone, again leading to abnormal test results. In this case, even if the egg is ready for fertilization, the test will be negative.
The test results may also be affected by taking certain medications.
When purchasing a drug to determine ovulation at a pharmacy, you must pay attention to the tightness of the packaging and the expiration date of the test.
Women should remember that an ovulation test cannot show a positive result if pregnancy has already occurred. Expectant mothers do not produce LH in their bodies.
If pregnancy has already been determined earlier, but urine testing for ovulation gives a positive result, this is extremely danger sign. In this case, there may be a frozen pregnancy or a threat of miscarriage. All this is very dangerous and requires consultation with a specialist. The doctor should order an ultrasound examination and find out what is the reason for such test indicators.
Medical statistics say that about 40% of women on the planet are diagnosed with frozen pregnancy. In most cases, everything ends in an arbitrary miscarriage, the cause of which is the arrest of fetal development.
