Ovulation refers to the day when a woman's eggs are released from her ovaries, and it is also one of the important periods for women to become pregnant. Although determining ovulation varies from person to person, most people can predict it by:

2. Measure body temperature: Women can determine their ovulation period by measuring their body temperature. In the middle of the cycle, the body temperature usually rises by about 0.5 degrees, which lasts until the last two days of the cycle.

3. Observe vaginal secretions: Women will secrete thinner vaginal secretions during ovulation, which may become clear, transparent, and colored.

4. Use ovulation prediction tools: There are many ovulation prediction tools available on modern browsers and app stores that can predict a woman’s ovulation period based on her menstrual cycle and health status.
