Ovulation is the day when it is possiblefertilization, as the mature egg leaves the ovary and is ready to meet the sperm. The life of the egg lasts only 24 hours, which is the time allotted for its fertilization.

Methods for calculating ovulation

This is why many couples planningpregnancy or, on the contrary, those who want to avoid it, try to calculate the day of ovulation. But this is not always correct and not for everyone, since there are many factors affecting the body. Because of this, an imbalance can occur, that is, the menstrual cycle is disrupted, various diseases appear, etc. Nevertheless, there are ways to calculate the day of ovulation, observing certain rules.

Calculate the day of ovulation with a calculator

This method is effective only ifthe woman has a regular menstrual cycle, if not, then the information cannot be considered accurate, especially if the day of ovulation is calculated for the purpose of contraception. You can use both an online calculator presented on various women's websites and for independent calculations. If there is an opportunity to connect to the Internet, then everything is much simpler. In the online calculator you will need to enter the necessary data, and the program will calculate everything itself. If you want to make the calculation yourself and find out how this method works, then this is done as follows. You need to know the date of the onset of the next menstruation, subtract 12 from it, and then another 4. Ovulation occurs in the interval between the resulting days. For example, the next menstruation should be on December 19, then 19-12=7, 7-4=3, therefore, ovulation is possible from December 3 to 7.

Know the body language

Of course, this cannot be accurate.indicator, since not all girls know about all the manifestations of their body, but there are girls who are so sensitive that they can determine the day of ovulation by the signs that the body gives.

• pain in the lower abdomen - may not manifest itself inall, much more often ovulation occurs painlessly, but keep in mind that the pain can be nagging, can cause mild discomfort, but it should not be dull or strong cutting pains, if this is observed constantly, you need to see a doctor;
• discharge - you can determine ovulation by"raw egg white", that is, by the discharge, very much resembling it. It is very important to observe what exactly they look like. After the end of menstruation, there is no mucus, then it appears gradually, over time it becomes sticky, creamy, then watery. These discharges become more viscous and thick at the time of greatest fertility. The older a woman becomes, the fewer days she has such mucus;
• position of the uterus - before you startexamination, wash your hands thoroughly. The uterus has the property of changing in size, namely, on ovulation days it is open, soft, raised, moist, on normal days it is located lower, drier and harder to the touch.

Thus, observing the changes in the body,you can determine not only the onset of ovulation, but also see how the entire body works, which means that if there is a disruption in its functioning, you will be able to identify it in time and consult a doctor to eliminate the disease.

Measurement of basal body temperature

This method is preferred by many girls andwomen, it is recommended by doctors, because it is economical, one of the most accurate, it can be used independently at home. This is possible due to the fact that body temperature under the influence of hormones can decrease or increase. Therefore, measuring the basal temperature shows the work of the female body, the onset of ovulation, the absence or onset of pregnancy. To use this method, the temperature should be measured for at least 3-6 menstrual cycles. Only then will the overall picture be clear, and you can decipher the data obtained. In addition, in order to determine the day of ovulation using basal temperature, you need to know some rules, only under these conditions will everything be done correctly:

• measure the temperature at the same time every day in the morning;
• basal temperature is measured after a calm night sleep lasting at least 3-6 hours;
• the mercury thermometer should be measured, the rest are considered less sensitive and less accurate, for this take one thermometer and throughout the measurement time use only it;
• the temperature should be measured through the mouth, rectum or vaginally, mainly measured through the rectum;
• stopping the choice on one of the measurement options, stick to it at all times;
• When taking a vaginal measurement, insert the thermometer up tomiddle, the temperature is measured for 5 minutes, through the oral cavity, hold the thermometer under the tongue for 3 minutes, through the rectum - lubricate the tip of the thermometer with baby cream to make the measurement procedure less unpleasant, hold for 5 minutes;
• children's cream, a thermometer must be prepared in advance from the evening, so that in the morning you can do everything calmly, without unnecessary movements;
• Before measurement it is impossible to rise, make sharp movements, prepare a thermometer so that it was possible to reach to it by slow movement;
• it makes no sense to measure the temperature inIf you: get sick with viral diseases, take contraceptives, drugs that were forbidden during temperature measurement, took alcohol on the day before, entered the day before the measurement into sexual intercourse;
• the obtained data should be entered into the table, after which a schedule will be drawn on which you can see if the onset of ovulation has occurred.

When measuring your basal temperature, please note:Please note that after the appointed time, the temperature will rise every hour, and these indicators cannot be considered accurate. If, for example, you woke up earlier to go to the toilet, but then want to lie down again, then you first need to measure the temperature and only then do other things. The basal temperature on the chart will be the boundary between the first and second phases of the cycle. On the day of ovulation, as a rule, the temperature is considered the lowest, and then it rises. This phenomenon is completely normal, since under the influence of the hormone progesterone, the body prepares for pregnancy, if fertilization does not occur, then before menstruation the temperature returns to normal again, gradually decreasing. This method has its pros and cons. Advantages:

• inexpensive method - the only thing you need to buy is a thermometer to measure basal temperature;
• suitable for women with irregular menstrual cycles;
• the method can also be used later to prevent unwanted pregnancies (sexual intercourse should be avoided during the most fertile days).

Disadvantages of the method:

• inconvenience - it is necessary to measure the temperature every morning, and the nature of cervical mucus should be monitored throughout the day;
• if you suddenly get sick, all the results will be in vain, because the disease and even the change of climate or work can lead to a disruption of the menstrual cycle, which will cross out the whole picture for this month;
• for a relatively accurate definition of the day of ovulation, tracking should be at least 2-3 months, preferably six months.

Pharmacy tests

This is a good method that works on the principlemeasuring the level of luteinizing hormone in urine. Such tests can be purchased without a prescription at any pharmacy. But they are a good helper only if you have a regular menstrual cycle and do not have a deficiency of luteinizing hormone. In the second case, the test may show that there was no ovulation, although in fact it occurred. But with a regular cycle, you can use them. The tests show a positive result already a day before ovulation, this gives additional time to plan your sex life for the purpose of possible conception of a child. The principle of such tests is based on the fact that the level of luteinizing hormone increases before ovulation, therefore, an egg will soon be released from one of your ovaries. When calculating, if the second strip on the test is weak, it should also be taken into account. The advantages of this method are greater accuracy, convenience than when measuring basal temperature, and predicting ovulation 6 hours before it occurs, which makes it much easier to choose the time for intercourse. In addition, you do not need to do calculations every day, it is enough to use the test in the middle of the cycle. When buying, do not forget to look at the expiration date. But there are also disadvantages. These tests are not an economical option, since they are quite expensive, and you will have to spend 20-50 dollars on them for one cycle. This method does not work well for women with an irregular menstrual cycle. In addition, if you take drugs that help improve fertility, the ovulation test may show an unreliable result. These are the most common options for calculating ovulation. Which method to use is up to you: plotting basal temperature changes or simply buying a test at a pharmacy.
