The female menstrual cycle is regulated by several hormones that control the maturation of the egg, its release from the ovary (ovulation), and the condition of the endometrium. During the cycle, there are days on which conception is most likely. Sometimes situations arise in which it is necessary to determine in which part of the cycle these days begin.
It is necessary
- - notebook;
- - a pen;
- - the calendar;
- - thermometer
Instructions
Step 1
In order to determine in which part of the cycle you ovulate, start a separate notebook in which you will make calculations.
Step 2
Mark the day your period starts on your calendar. This is the first day of the cycle. Calculate how long your cycle is. Ovulation usually occurs two weeks before the end of the cycle.
Often in the antenatal clinic, doctors issue special calendars to keep track of the menstrual cycle, which are very convenient to work with.
Step 3
During the cycle, the so-called basal temperature changes. To measure your basal temperature, you will need to measure the temperature in your vagina or rectum for 5 minutes every morning after at least three hours of sleep. High precision thermometers must be used. Write down the thermometer readings in a notebook. At the beginning of the cycle, before ovulation, the basal temperature will be about 0.2 ° C lower than after ovulation. This moment of temperature rise is the period of ovulation.
Step 4
You can buy ovulation tests in almost every pharmacy. They measure the level of luteinizing hormone in the urine. The moment the test shows a positive result, ovulation occurs.
Step 5
Ultrasound diagnostics helps to determine the day of ovulation most accurately: the doctor conducts an ultrasound of the ovaries and reports after what time ovulation is expected. It is better to come to the appointment not at the very beginning of the cycle, but closer to the middle. The disadvantage of this method, of course, is the cost, as well as the waste of time.
Step 6
In addition to the above methods, some women are guided by indicators such as a change in the nature of vaginal discharge or ovulatory pain, but these signs are rather blurred, and they should be observed only together with the rest.
Step 7
So, after you have figured out which days of the cycle ovulation occurs, you can conceive. Since sperm can live in the female genital tract for up to 5 days (according to some sources - up to 7), then, respectively, about 5 days before ovulation, days favorable for conception begin. This period ends about 3 days after ovulation.
