Ovulation and conception calendar online
Calculating ovulation online is one of the fastest, most accurate and effective ways to determine your fertile (fertile) days yourself. To do this, use the conception calculator, which calculates and displays the days of fertility in a period of four months.
To carry out an online calculation of ovulation, you must enter the following data:
- First day menstrual bleeding of the cycle you are interested in (if you are interested in the days of ovulation in this and the next three months, then you must enter the first day of the last menstruation; if you want to know on which days of the previous cycles you had ovulation, you must enter the first day of the menstruation of the corresponding cycle);
- Average duration of menstruation;
- The duration of the regular cycle. If the cycle irregular, you must first analyze the duration of the cycle for the last 6 months, and determine the minimum and maximum number of days of the cycle. Check the "irregular cycle" checkbox, enter the minimum number of cycle days in the left window, and the maximum number in the right window that appears;
- The duration of the phase of the corpus luteum, which is usually determined by the laboratory method by the level of the hormone progesterone, averages 12-16 days (by default, the program has a duration of 14 days).
After that, you just need to click the "Calculate" button, after which the program will display an accurate calendar, which will indicate the days of the expected ovulation (with a percentage probability), as well as the days of safe and conditionally safe sex. Online ovulation using such a calculator is calculated with fairly high accuracy.
How does ovulation happen?
Normally, the female menstrual cycle, which is counted from the first day of bleeding to the first day of the next period, lasts from 28 to 35 days.
On average, favorable days for conception (they are also called fertile) fall in the middle of the cycle, and include 1-2 days before ovulation, the period of ovulation itself and 1 day after ovulation. The average duration of the state of fertility is 7 days.
That is, the fertile period begins at the time of the jump in LH levels. If during this time the sperm does not fertilize the egg, it simply dies, and the new one matures only in the next cycle.
Corpus luteum phase (luteal phase)
After the end of ovulation (follicular phase), the period of maturation begins corpus luteum - luteal phase, which is characterized by a decrease in the level of the hormone LH and an increase in the production of progesterone. The corpus luteum is responsible for the production of hormones necessary to maintain the normal course of pregnancy. If pregnancy does not occur, then the corpus luteum dies, the level of progesterone decreases, which provokes the onset of menstruation.
Normally, the duration of the luteal phase ranges from 12-16 days... Insufficiency of the phase of the corpus luteum (duration 10 days or less) or its duration more than 16 days, speak of hormonal disorders, which may result in early miscarriage.
Recall that the corpus luteum phase begins the day after the end of ovulation and lasts until the onset of menstruation. That is, to calculate the duration of the corpus luteum phase, you need to know the duration of your menstrual cycle, the middle part of which falls on ovulation, and the days following it - on the luteal phase.
In a healthy woman, ovulation occurs every month (and sometimes twice), but there are two to three months a year when the egg does not mature - such cycles are usually called anovulatory, and they are also considered a variant of the norm.

Having determined favorable days for conception, it will be quite simple to calculate the optimal number of intercourse during this period, and the chances of getting pregnant will increase significantly. It should be noted that the ovulation schedule will be useful for those who want to prevent unwanted pregnancy, because it is often used as a method of contraception.
How to calculate the ovulation calendar?
Physiological signs of ovulation
Gynecologists say that every woman can notice the signs of ovulation and calculate conception - for this you just need to carefully monitor your body.
- Features of discharge... Vaginal discharge is a constant occurrence in every woman, but in different phases of the menstrual cycle, they have a different character. So, before ovulation, they become transparent and liquid, or stringy, and in consistency resemble the protein of a chicken egg. In addition, during this period, some women observe brownish or bloody discharge (the so-called daub). If ovulation does not occur, the discharge is sticky, creamy, or absent altogether.
- Discomfort in the lower abdomen... The release of the egg can be accompanied by unpleasant sensations in the area of the ovary in which the dominant follicle has matured. They can last from a few minutes to a few days, and resemble the "stretching" of the abdomen before your period.
- Swelling and pain in the mammary glands... Under the influence of hormones in many women, before the release of the egg, the breasts may become tender or sore.
- Increased libido. Scientists have proven that it is on the eve of ovulation that women experience the greatest sex drive - this is due to the natural instinct of reproduction (thus the body tries to increase the chances of pregnancy).
- General changes in well-being. Such signs are individual for each woman - it can be an exacerbation of taste and olfactory sensations, increased efficiency, or, conversely, irritability and increased emotionality.
Calendar method
First of all, it should be noted that each woman has an individual conception calendar, which can be calculated based on the characteristics of the body.
With a regular cycle, if your period is literally "by the clock", the question of how to calculate ovulation is usually not a big problem, because for this you will have to carry out the simplest calculations. For example, if a woman's cycle lasts 28 days, you can simply divide this figure by two: 28/2 = 14. That is, in this case, days starting from the 12th day will be considered fertile.
However, this method cannot be called extremely accurate. Very often, for a number of reasons, the menstrual cycle can be shortened or lengthened, respectively, the timing of the release of the egg also shifts, and when it is completely ineffective. That is, it is best not to rely on your own calculations, but to use a more convenient online ovulation calculator or measure basal temperature.
Basal temperature
Basal temperature (BT) measurement is one of the most effective methods and is best for women with irregular cycles. To understand how to calculate the day of ovulation in this way, you should know some of the features of the female body.
During the menstrual cycle, the basal temperature changes several times - this happens under the influence of hormones. At the beginning of the cycle, it is quite low, and during ovulation it rises significantly, reaches 37-37.3 C, and remains at this level until the next menstruation. True, to accurately determine the days of conception, it is very important to follow a number of rules:
- You need to measure the temperature in the morning at the same time, after a full night's sleep (at least 6 hours), without getting out of bed.
- Use the same thermometer, preferably a mercury one.
- The thermometer is inserted into the anus, vagina or placed under the tongue, after which you need to lie down quietly for 5 minutes.
- To obtain accurate results, BT should be measured for at least two cycles, recording the results.
It should be noted that in this way you can calculate ovulation online. There are special resources and programs on the Web that calculate fertile days automatically (a woman only needs to enter BT indicators there every day).
Read more about measuring basal temperature in the section.
Ovulation test
Ovulation tests are special strips similar to those used to determine pregnancy. True, the marker in this case is the hormone LH, not hCG. Measurements are carried out in a similar way (immersion of the strips in urine), and should begin 2-3 days before the expected ovulation.
The instructions for the test indicate on which day of the cycle it is best to start measuring, depending on the duration of the cycle, but with irregular periods, it is almost impossible to determine this time.

Laboratory methods
One of the ways to create an ovulation calendar, calculate fertile days and quickly get pregnant is to get tested for the main female hormones. These include:
- FSH - surrendered on the 3-5th day of the menstrual cycle;
- LH - for 3-8 or 21-23 days;
- Prolactin - 3-5 or 19-21 days;
- Estradiol - on days 4-7 and 6-10;
- Progesterone - 6-8th day.
The concentration of these hormones varies depending on the phase of the cycle, therefore, based on the test results, it is possible to determine the day for conception with great accuracy.
If you ask specialists the question of how to determine ovulation most effectively as in any cycle, the answer will be unambiguous - control of follicular growth using ultrasound.
To do this, it is necessary to carry out several ultrasound procedures: the first - on the 7-8th day, the second - on the 10-12th, the third - at the request of the woman or the doctor's recommendation. The sign of ovulation is usually the size of the dominant follicle, which is 18-21 mm. In addition, later you can check whether the follicle has ruptured - if a corpus luteum has formed in its place, it means that ovulation was normal.
Ovulation occurs at that moment in a woman's menstrual cycle, when a mature egg leaves the ovary, descends into the fallopian tube, where it can fertilize if it comes into contact with the sperm. Since conception can only occur during ovulation, many women find it helpful to calculate this period when planning a pregnancy. Calculation of the onset of ovulation is not recommended as a substitute for other methods of contraceptive measures due to the inaccuracy of the prognosis and the possibility of sperm survival in the female reproductive tract for up to seven days. For the most reliable results, calculate when you ovulate using more than one method and track the data over many cycles.
Steps
Calendar method
- Track the number of days in each cycle, including the day you started your period. The last day of each cycle is the day before the next period starts.
- Continue to track your cycle this way for 8-12 cycles. The more cycles you can analyze, the more accurate the calendar method will be.
-
Create a table of cycle times. When you have records of at least eight cycles, you can convert that data to a table. In one column, list the days of the month when your period started, and in the second column, write down the number of days in that cycle.
- In addition, you can use online ovulation calculators, there are many such applications on the Internet. Be sure to include in the calculation all the information specified above, otherwise the forecast will not be entirely accurate.
-
Use your spreadsheet to predict fertility in the current cycle. It is difficult to determine the exact day of ovulation using only the calendar method. The calendar is useful for determining the number of days that you will be fertile, which may vary for each woman. To determine these days, you must:
Analyze the test. Pee on the stick and wait until a new line appears in the test window. A line as dark as the existing control line suggests that you are probably ovulating. The weak line is not a reliable indicator.
Repeat as needed. Take the test every day at the most likely times in your cycle, as described in the calendar method. If you missed ovulation in previous cycles and can afford to purchase additional tests, you can do ovulation tests twice a day.
Track your menstrual cycle using other methods as well. This is not the most accurate method, but it is a simple and rewarding step to take while tracking other data as well. Buy or create a calendar to start tracking your monthly menstrual cycles. Circle the first day of your cycle, which is the day you started your period. Keep track of your cycle times, which are typically 28 days on average.
Identifying infertility
Note that there are no expected changes. By using basal temperature readings, an ovulation test kit, and a cervical mucus test, you can find that there are no expected changes associated with ovulation and a normal menstrual cycle. A single case like this does not necessarily mean that you are infertile. This could mean that you missed a short LH surge between ovulation tests, for example. However, if you are experiencing interruptions in multiple cycles, or you have a short time window for conception, you should probably take the steps below.
See your doctor. Your obstetrician / gynecologist or reproductive endocrinologist may perform tests that are more accurate than the home methods outlined here. This can be a blood test to measure levels of progesterone and other hormones, or tests to detect abnormalities in the thyroid gland or abnormal prolactin levels, if deemed likely by your doctor. An ultrasound test may be done to look for abnormalities in the structure of the reproductive tract that can affect ovulation.
Ask your sexual partner to get tested as well. Men can also get tested for infertility. This usually starts with a sperm cycle check, and may continue to an ultrasound scan to look for possible problems with the male reproductive system.
Consult about treatment. If your doctor suspects that you are infertile due to a lack of ovulation, they may recommend one of a variety of medications, depending on your specific situation. Do not assume that conception does not occur due to a lack of ovulation without receiving an official diagnosis from a specialist, since there are many other possible reasons for this. The doctor should also investigate the likelihood of tubal obstruction, problems with sperm, problems with the seating of the uterus or oocyte, and age-related decline in oocyte quality.
Ovulation, which you can calculate the date of right now, is the only day of the month when a woman can get pregnant. Many ladies use the opportunity to calculate ovulation online in order to bring the long-awaited motherhood closer. Other women, on the contrary, try to protect themselves from unplanned pregnancy in this way. But, unfortunately, both programs and doctors can be wrong. And if in the first case, the calculation of ovulation by a calculator is done rather for the sake of interest, then in the second, an incorrect result can lead to very negative consequences. So, you should not pin all your hopes on this method alone.
But if you do decide to try, then you should understand what ovulation is, how to calculate it and what you need to know and be able to do.
One of the most popular, affordable and reliable methods is charting basal temperature measurements. To compile it, you will need to measure rectal temperature in the morning for at least 3 months every day, while not forgetting to enter all the data obtained in the plate in order to draw up a schedule later.
The next way is to determine when ovulation occurs using a test, to calculate, or rather to clearly see the result, without using a calculator or a graph. The test must be done for several days in a row. The test strip itself is practically no different from the one used to determine pregnancy, and the technique is also not new. The only difference is in chemical reactions.
Ovulation, calculate, calculator, all kinds of tests and graphs, ultrasound - all these terms and actions are so difficult and expensive. But you can trust your own feelings! When a woman's body is ready to conceive, it begins to give some signals. First of all, this affects the sexual desire - it becomes noticeably stronger. The amount of vaginal discharge also increases. But the main thing here is not to confuse this natural cyclical process with an infectious disease. Some women may feel discomfort in the area of the ovary where the egg has matured. Well, to confirm the reliability of all the above signs, to find out whether there was ovulation, to calculate online, using a calendar - all this is not a problem.
But keep in mind that the only 100% method for calculating this favorable, and for some - dangerous day, is an ultrasound scan.
Every woman, especially when the moment of pregnancy is right, should be attentive to her health. One part of this process is tracking your menstrual cycle and ovulation. To make the process more efficient, we offer an online calculator that will allow you to determine the favorable days for conceiving a child.
We suggest using the service "Calendar of conception and contraception" - by indicating the initial data: the first day of the cycle and its duration, you can determine favorable days for the conception of a boy or girl, the beginning of the next cycle, ovulation. The conception calendar cannot guarantee a 100 percent result, since a lot depends on the body and everything is individual. The work of the calendar is based on average statistical data.

What is a calendar?
The conception calendar is an online form in which you just need to enter the first menstruation and the duration of the cycle. The program itself will calculate when ovulation will occur, and which days will be the most successful for fertilization (and dangerous for someone!).
To make the operation of the program that calculates the date of ovulation and the onset of pregnancy clear, we will give the main factors that were taken into account when creating it:
- Many women (although it all depends on the individual factor) ovulation occurs towards the middle of the cycle. The calculator calculates the middle of the time interval after the beginning of menstruation and their end, and also calculates, taking into account the most dangerous or, conversely, favorable days on which pregnancy can occur
- Fertilization. Does not occur during menstruation and at the end of the cycle: on these days, conception almost does not occur
The calendar also calculates relatively safe days when pregnancy is unlikely. These are the days at the beginning and at the end of the cycle. In the middle of the cycle, the calculator marks the day of ovulation, and can also determine the day of the beginning of the next period.
To calculate the days of ovulation, you just need to enter your period data into the online calculator. After that, press the button, and the calculator itself will calculate the day of ovulation and a favorable day for conception. Of course, there is no guarantee that the indicated data will be absolutely accurate, but they will be able to roughly indicate to you the dangerous days on which ovulation and the onset of pregnancy occur.
The calculation of the day of ovulation and potential pregnancy can be done for a whole year. This way, you will know in advance when to plan intercourse, depending on whether you want to get pregnant or not.
The form of the calendar is very easy to use. The required days are marked in different colors, so that they immediately catch the eye. The pregnancy calendar will help you speed up the conception of a child and get closer to the long-awaited event.
How to determine the gender of a baby?
Any parent who wants to have a child thinks about how to calculate its gender. Traditional and traditional medicine offer different ways to do this.
A calculator for determining the sex of a child is another technique, however, it does not give 100% of the result. The conception calendar of a girl or boy can be compiled for yourself if you use the same pregnancy calendar. The conception calendar for a girl or a boy is based on the theory that a girl is obtained if sperm cells entered the woman's body before ovulation and stayed there for several days. If the sperm cells entered the body of the expectant mother immediately after ovulation, then it turns out a boy.
The conception calendar for a boy or girl, of course, also does not give a 100% guarantee, but it allows you to get closer to the desired result. Doctors have proven that fertilization after ovulation leads to the birth of a boy, and before ovulation - a girl.
After you have learned the favorable days for conceiving a child and determined what gender the baby can be, it is time to plan a pregnancy.
To calculate dangerous or, conversely, favorable days for conception after menstruation or to determine the sex of the child, a woman will have to record some data about herself and her health. This data will help her create her own calendar of conception of a boy or girl. However, it is worth remembering that the day of ovulation and favorable days for conceiving a child of one sex or another, calculated by an online calculator, are relative. The body of every woman is individual and unique, and many more factors affect the determination of the sex of the child.
