How to calculate a woman’s ovulation period?

Method 1: Basal body temperature method

A woman's basal body temperature changes with her menstrual cycle. On the 14th day of the menstrual cycle, body temperature reaches its highest value and then begins to decrease. If the cycle is 28 days, then a woman's body temperature changes cycle is 14 days. You can use a thermometer to measure your body temperature and record the time it changes.

Method 2: Calendar method

Record a woman's menstrual cycle on a calendar and calculate ovulation based on the cycle on the calendar. In a woman’s menstrual cycle, the first 14 days are the safe period and the last 14 days are the dangerous period. If the cycle is 28 days, then the danger period is approximately day 13 to day 21.

Method 3: In vitro fertilization

If neither of the above methods is able to predict a woman's ovulation period, you may consider using in vitro fertilization. In a woman’s menstrual cycle, the first 7 days are the safe period and the last 8 days are the dangerous period. Pregnancy is possible if a man fertilizes a woman in vitro before day 7 and after day 8 of her menstrual cycle.

The estimation of a woman's ovulation period needs to comprehensively consider the woman's menstrual cycle and physical condition. If your cycles are erratic or you have health issues, you may want to consider using other methods to predict when a woman will ovulate. The most important thing is to ensure that the man is fertilizing her in vitro during the woman's menstrual cycle to ensure that the chance of pregnancy is minimized.
