The method for determining the day of ovulation is necessaryChoose individually according to "your own case," and do not use for this purpose online tests to determine the day of ovulation, which offer to go through most of the women's sites.

Do not trust the ovulation test online -It's the same as taking a finger in the sky! They work according to this scheme: the program divides in half the duration of your menstrual cycle (that is, the number of days from the last day of previous months to the first day of the next monthly period - on average, the cycle lasts 21-35 days). Further, the number of days is counted from the last day of previous months, and here is the "supposed" day for ovulation, which in some cases is not true!

Test of ovulation

Determination of the day of ovulation with a home test strip for ovulation

Using the ovulation test, you can determineThe most favorable time for the conception of a child. Ovulation is the emergence of a mature egg from the ovarian follicle into the abdominal cavity of a woman. Ovulation is the period when the egg is ready to conceive a child. This period lasts 24-36 hours from the onset of ovulation.

How can I use the ovulation test?

First, you need to know the length of yourMenstrual cycle. The menstrual cycle is a period that starts from the first day of menstruation and ends with the day before the next menstrual period. Menstruation is a biological process, during which there is a monthly bloody discharge from the uterus, commonly referred to as "menstrual".

For example, if the previous monthly started 8April, and the following began on May 6, the period from April 8 to May 5 is a menstrual cycle lasting 28 days. The menstrual cycle in a healthy woman can last from 21 to 35 days.

What are the stripes on the test?

The test strip reacts to the contentLuteinizing hormone (LH) in a woman's urine, the level of which with the approach of ovulation increases significantly, which is displayed on the tester as two bright strips. One of the strips is the control one, and the other is the test one. The test strip is the same strip that indicates the approach or onset of ovulation.

The test strip appears during testingAlways, if the test is carried out correctly. It is necessary for visual comparison with the test strip. That is, the control and test strips should be the same in brightness or the test strip is more intense in color than the control strip, only then you can judge about the onset of ovulation.


How to use tests for ovulation?

  1. Collect the urine in a clean and dry jar forAnalyzes (sold in a pharmacy for about 12 Russian rubles or 3 UAH per piece) or in a special container for urine, which comes with some tests. The test for ovulation can be done at any time of the day, but preferably in the interval from 10 am to 8 pm. But urine should not be the first morning, i.e. Do NOT collect urine immediately on waking. It is important not to drink a lot of water before testing, and do not urinate 2 hours before the test for ovulation. And it is also desirable to perform the test at the same time each time.

  2. Take the test strip from the bag and lower it into the urine at the level indicated by the arrows for 5-10 seconds.

  3. After this time, remove the test strip from the urine and place it horizontally on a flat, dry surface.

  4. After 10 minutes (not later), analyze the result.

If the test strip is paler than the control,Hence, the day of ovulation is approaching. If the test strip is the same in brightness or more saturated in color than the control strip, then ovulation will occur within 24-36 hours. The absence of a second strip indicates that there is no ovulation on this day.

When should I start an ovulation test?

Knowing the length of your menstrual cycle(With a regular cycle) or the duration of menstrual cycles in the last 4-6 months (with an irregular cycle), determine the first day of the test according to the table. If the cycle is irregular, select the shortest cycle and determine the day of the first test.

Ovulation schedule

An example of using a table. If the length of your cycle is 29 days, then the first test should be carried out on the 12th day from the moment of the onset of menstrual bleeding (menstruation). For example, if the menstruation started on March 5, then with the 29-day menstrual cycle, the first test should be conducted on March 16.

To determine the exact day of ovulation, the test should be performed once a day for the remaining 4 days.

Dignity: high accuracy in determining the day of ovulation.
Disadvantage: high cost.

  • The cost of the Ovuplan test is about 170 Russian rubles. (Somewhere 45 UAH) for 5 test strips.

  • The cost of Frautest for ovulation is 300-350 Russian rubles. (80-90 UAH) for 5 test strips and a container for collecting urine.

  • The cost of the test Eviplane - from 280 Russian rubles. (From 72 UAH) for 5 test strips.

  • The cost of the Ovupulse test is about 47 Russian rubles. (Somewhere 12 UAH.) For 1 test strip.

Ultrasonic monitoring of the growth and development of follicles (folliculometry)

Folliculometry is the medical observation forChanges in the ovaries and uterus throughout the menstrual cycle. With the help of ultrasound monitoring, it is possible to judge the correctness of the development of follicles, the presence and flow of ovulation, the status of the uterus and ovaries in general, and to identify some disorders that prevent the onset of pregnancy.

To determine the day of ovulation withFolliculometry the first examination must be completed on the 8-10th day of the menstrual cycle. Repeated examinations are prescribed 2-3 days after the first and carried out before ovulation. And if ovulation for some reason did not occur, then until the onset of menstruation.

The exact time of ultrasound monitoring is determined by the specialist of ultrasound depending on the individual characteristics of the organism of the woman being examined, and the results of previous examinations.


Signs of normal ovulation are the following facts that can be established with the help of ultrasound:

  • The dominant follicle developed to "ovulatory dimensions" (18-24 mm);

  • There is a rupture of the dominant follicle and the appearance of a yellow body in its place;

  • There is the appearance of free fluid in the anterior space.

A week after ovulation in the body of a womanIncreases the level of progesterone, which will help determine the blood test. A high level of progesterone in the blood is the final sign of the normal course of ovulation.

The reasons for which ovulation may not occur are such violations:

  • Atresia (or regression) of the follicle - underdevelopment of the dominant follicle or arrest of development and regression (decrease) in its size;

  • Persistence of the follicle - the developed dominant follicle does not break, and the egg does not exit into the fallopian tube;

  • Follicular cyst - the developed dominant follicle does not break, besides it continues to increase in size (more than 25 mm), forming a follicular cyst;

  • Luteinization of the follicle - the follicle does not break,But begins to "wrinkle" slowly and turns into a yellow body with an egg in the middle. Premature luteinisation is also observed, which is also an anomaly.

Conduct folliculometry shouldA qualified specialist, otherwise in the correctness of the analysis of the data obtained and in the established diagnosis as a whole, one can doubt. An experienced specialist will select the necessary treatment according to a certain clinical picture.


  • The most accurate method for determining the day of ovulation, provided that the obtained ultrasound is analyzed by an experienced specialist in this field;

  • The possibility of determining pathologies at different stages of the process of maturation of follicles and violations in "female" health in general.


  • Expensive method.

Method for the analysis of cervical mucus

Throughout the menstrual cycle in the bodyWomen there are a number of changes that have been combined for convenience in phases. The first phase is the maturation of the egg. The beginning of this period is the first day of menstruation. Depending on the characteristics of the woman's body, the first phase can last from 7 to 22 days, but on average it lasts about 14 days. In the first 3-6 days, the endometrium of the uterus is peeling off, in other words, menstruation, and bloody discharge is observed. Several days after menstruation are called dry. In these days, cervical mucus (or mucus discharge from the cervix) is absent or thick and viscous, forming a so-called mucous plug in the cervical canal, which prevents the penetration of infections and the progression of spermatozoa into the uterus. This period is called safe, since the probability of getting pregnant is almost zero. At the end of the first phase, the dominant follicle reaches its maturity.

The second phase is called ovulatory. During this period, the mature egg is released from the follicle and moving into the fallopian tubes, remaining there in anticipation of fertilization for about 2 days. The ovulatory phase lasts for 3 days, and the sign of its onset is transparent liquid, slippery discharge. To analyze and control the nature of secretions, one can observe the mucus on the underwear or insert two fingers into the genital tract. When the cervical mucus can be stretched between the forefinger and the thumb by 10-12cm, then ovulation has occurred.

For conception planning or for protection fromAn unwanted pregnancy is important to determine the onset of this particular phase of the menstrual cycle. After 2-3 days before ovulation and the day after it - this is the most favorable days for the conception of the child. For convenience, these days were called wet, since in this period of time there are abundant discharge, in consistence and color resembling egg white. Such mucus facilitates the movement of spermatozoa to the egg, besides it is enriched with nutrients, which spermatozoa need for further movement and existence in general.

Children's shoes on the calendar

The third phase is secretory. The duration of this phase is more or less constant and is 11-16 days. For this phase, there is a sharp reduction or cessation of discharge, or the presence of turbid, sticky mucus. This phase of the menstrual cycle is also called dry. The probability of becoming pregnant is minimal. If fertilization does not occur, then the egg dies off as unnecessary. In the body, the upper layer of the uterus dies, thus preparing for the onset of a new menstrual cycle and possible fertilization in general. The woman again has menstruation.

If the pregnancy has occurred, the woman's uterus is preparing for the implantation of an ovum fertilized with a sperm cell. Menstruation does not come.

We note that in the case of an individual singularityOrganism, as well as infectious and fungal (for example, thrush) diseases of separation from the genital tract can become a hindrance or a "false helper" in determining ovulation, so this method of determining ovulation is considered accurate and reliable - it is impossible.


  • With independent observation of the nature of mucus (without visiting a gynecologist) the method is absolutely not costly.


  • Not high accuracy of the method due to various factors, for example, the latent course of some diseases "in a feminine way" does not allow us to correctly determine the day of ovulation;

  • For greater accuracy, it is advisable to combine several methods for determining ovulation;

  • Observations should be made systematically.

Method for determining the day of ovulation at basal temperature

Method for determining the day of ovulation based onMeasuring basal temperature is the least expensive in terms of finances, but you need to follow all the instructions of this method responsibly to accurately determine the day of onset of ovulation.

So, what is basal temperature and howDoes this method work? Basal temperature is the body temperature, measured in the morning by oral, vaginal or rectal (in the rectum) method in a state of complete rest.

Baseline temperature measurement rules.

Basal temperature (BT) can be started to be measured on any day of the menstrual cycle, but for convenience it is better to start from the first day of menstruation.

Measure basal temperature for oneCycle follows the same thermometer and only one method you selected (oral, vaginal or rectal). The temperature measured in the armpit, in this case is not suitable for determining the day of ovulation!

If it is more convenient for you to measure the temperature by the oral method, then the thermometer should be placed under the tongue and the temperature should be measured with the mouth closed for at least 5 minutes.

If you prefer vaginal or rectal method of temperature measurement, then the thermometer should be kept for at least 3 minutes.

The temperature should be measured immediately afterAwakening, without getting out of bed and without making unnecessary gestures. Therefore, the thermometer should be kept near you at arm's length, and you should shake the mercury or alcohol thermometer beforehand (before going to bed) in order to not spend energy on it in the morning, otherwise the measurement result will not be accurate.


Basal temperature measurements should be performed every morning strictly at the same time.

Immediately after measuring the temperature, note the result of the measurement on the graph of BT, the template of which you can download below, and for convenience print it on paper.

Daily noting in the chart the measured basalTemperature, you get a curve, analyzing which you can judge about the onset of ovulation. So in the first half of the cycle (ie before the onset of ovulation) the basal temperature is below 37 ºС, and varies somewhere in the range of 36.5-36.7 ºС. In the second half of the cycle (ie after the onset of ovulation), the temperature rises to 37 ° C or more. And the day before this increase is the day of onset of ovulation. Those. If the curve curve crossed the horizontal red line, then - ovulation has come.

If the measurements are taken correctly during3 months, it will be possible to approximately determine the day onset of ovulation. So 3-4 days before the jump in temperature and will be most favorable for conception.

It must also be said that the temperatureThe body can be affected by many external factors that do not accurately determine the day of onset of ovulation, so for convenience in analyzing the BT schedule, mark on it moving / flying, taking alcohol, medicines (hypnotics, hormones, soothing) or painful health.

Remember: if one of the rules is neglected - the reliability of the measurements will be low!


  • Availability and cheapness of this method of determining the day of ovulation;

  • According to the temperature graphsPresumably to judge some changes in the body of a woman, such as the reason for the delay in menstruation, the absence of ovulation or the onset of pregnancy, which later, of course, must be further confirmed by modern medical methods of diagnosis.


  • This method does not provide an opportunity to accurately predict the onset of ovulation in the future;

  • Fluctuations in temperature can occur the next day or a few days after the onset of ovulation, which indicates its error in determining the day of ovulation.

The calendar method for determining the day of ovulation

The calendar method for determining ovulation isThe simplest of all available methods. With a regular menstrual cycle, ovulation usually occurs 14 days before the onset of menstrual bleeding (monthly). So, for example, during the menstrual cycle in 29 days, ovulation occurs on day 15 of the cycle. However, 73% of modern women have malfunctions of menstrual cycles. Thus, with an irregular cycle, it is impossible to determine the day of ovulation with a calendar method, unfortunately, it is impossible, but it is quite realistic to assume.

The period of maturation of the egg usually lasts 2Weeks, and after the expiration of this time occurs ovulation - the most suitable time for conception of the child. Depending on the duration of the menstrual cycle, ovulation teaches on one or another day of the cycle. To determine the expected day of onset of ovulation with an irregular menstrual cycle is quite simple, it is only necessary for 4-6 months to mark the date of the onset of menstruation in the calendar. And then calculate the number of days from the first day of the month to the day before the next monthly. Make similar calculations for the last 4-6 months, and write down these numbers, for convenience, in a row. For example: 28, 28, 25, 28, 29, 27.

 Ovulation Calendar

Choose the longest cycle and the shortest, and subtract from each 14 days. In our example, this is 25 and 29 days.


  • 25 days - 14 days = 11 - i.e. On the 11th day in this cycle, ovulation fell.

  • 29 days - 14 days = 15 - respectively, on the 15th day of the cycle, ovulation fell.

As a result, we get the time interval in whichCan occur ovulation in a particular woman in this period of her life. That is, in this example, a woman ovulation can occur on any day from 11 to 15 days of the menstrual cycle, i.e. From 11 to 15 days inclusive, starting counting from the first day of monthly bleeding. For example, this woman started on a monthly basis on March 2, which means she should wait for ovulation from March 12 to March 16.

It is necessary to take into account the fact that, being inThe body of a woman, spermatozoa remain viable on average 24-36 hours. And the egg after ovulation can survive for about a day. Thus, it appears that 2 days before the expected ovulation and 1 day after it are favorable for conception. In our case, this is from March 10 to March 17 inclusive. That is, during this week it is necessary to actively engage in sex with a partner in order to become pregnant.

If the pregnancy has not occurred, perhaps in thisMonth of ovulation was not at all. A healthy woman under 30 years of age within the norm is considered the absence of ovulation in the menstrual cycle 2-3 times a year. With age, the number of anovulatory cycles increases.

 The calendar

In addition, the presence of ovulation does not speak of herUsefulness. Therefore, if the pregnancy has not come after a year of active efforts to conceive a child, you should seek help from a specialist. A qualified gynecologist will help you conceive, endure and in the future give birth to a healthy baby for the joy of parents and grandparents!
