Properly able to calculate the exact day of ovulation is a very important procedure. This will help a woman choose the days for successful conception or avoid unwanted pregnancy. We will try to describe in detail all possible methods how to correctly calculate the day of ovulation.
How to accurately calculate the day of ovulation?
If the duration of the menstrual cycle is 28 days, then ovulation occurs on the 13-14 day. To make sure that ovulation occurs, you can use the basal temperature measurement method. The method is fairly simple and consists of measuring the temperature in the rectum every morning without getting out of bed. The obtained values are marked on a special graph, measurements should be carried out for three cycles.
In the normal menstrual cycle, before ovulation, there is a slight decrease in the basal temperature to 36.5 ° C, and on the day of ovulation - a sharp rise to 37 - 37.1 ° C. This is due to the release into the blood of a large amount of the hormone of pregnancy - progesterone, which, acting on the center of thermoregulation in the hypothalamus, leads to a rise in temperature.
The second way to correctly determine the day of ovulation is to perform an ovulation test . Their action is similar to the action of pregnancy tests.
The ultrasound examination in dynamics during the menstrual cycle allows us to trace the growth of the dominant follicle.
Subjective signs of ovulation are moderate pain in the ovary region on the ovulation side, as well as an increase in the number of transparent mucosal secretions from the genital tract.
How to calculate the day of ovulation by calendar and table?
There are special on-line calendars that help to calculate the exact date of the onset of ovulation. To do this, enter the date of the last menstruation and the duration of the menstrual cycle (if it is regular) in special cells.
There is also a special table on which the control curve is marked - it is the dynamics of basal temperature in the normal menstrual cycle. On this graph, you should note your basal temperature, and then compare it with the control.
Thus, to determine the date of ovulation, you need to use several methods. Accuracy of measurement largely depends on the regularity of the menstrual cycle and the reliability of the selected methods. With long unsuccessful attempts to become pregnant, you should consult a competent specialist.
