Ovulation refers to the process of maturation and release of female eggs, which usually occurs between the 14th and 17th days of a woman's menstrual cycle. For people trying to get pregnant, it's important to know when ovulation occurs. So, how to calculate ovulation?

1. Record your menstrual cycle: Record your menstrual cycle, calculate the time of the next menstrual cycle, and then deduce the possible ovulation period based on this time.

2. Measure basal body temperature: Measuring basal body temperature can more accurately predict a woman’s ovulation period. When you wake up every morning, measure your oral temperature, then record the changes in body temperature and draw a body temperature curve.

3. Use a calendar or calculator: Using a calendar or calculator can help predict when a woman will ovulate. Between days 14 and 17 of the cycle, record the dates and calculate possible ovulation.
