Ovulation refers to the day in a woman’s menstrual cycle when her ovaries secrete eggs. During this period, the female's reproductive organs will begin to release eggs, which pass through the vagina and into the uterus, ready to be combined with sperm to form fertilized eggs. Therefore, the ovulation period is very important for women's reproductive health.

Method 1: Use the basal body temperature method

Basal body temperature refers to the body temperature measured when a woman wakes up every morning and does not perform any activities. By measuring basal body temperature, a woman's ovulation period can be determined.

To calculate a woman's ovulation period, you need to first determine her cycle. Generally speaking, the longer the cycle, the longer the ovulation period. Then, measure your basal body temperature every morning and record the results in a table.

Generally speaking, a woman's ovulation period occurs between the 14th and 20th day of the cycle. A woman's ovulation period can be calculated using the formula:

Ovulation period = cycle days - 14 days

For example, if a woman's cycle is 28 days, then the number of cycle days is 28 days, minus 14 days, it can be seen that the woman's ovulation period is from the 14th to the 20th day.

Method 2: Use the calendar method

A woman's ovulation period can be determined using the calendar method. Generally speaking, a woman’s menstrual cycle lasts 28 days, so the 1st to 10th of each month is the woman’s menstrual cycle. During this period, the female reproductive organs begin to release eggs.

In order to determine a woman's ovulation period, she can start recording her menstrual cycle on the 1st of each month. Between days 14 and 20 of the cycle, the woman's temperature and calendar are recorded so that the woman's ovulation period can be determined.
