Ovulation refers to the time when a woman's eggs are released from the ovaries to the fallopian tubes. It is also one of the most active days of the month for women. During ovulation, a woman's body temperature will rise and her body will undergo a series of reactions, which usually make it easier for a woman to become pregnant.

Here are some methods that can help determine ovulation:

1. Measure basal body temperature: When women wake up every morning, measure their oral or anal body temperature and record body temperature changes. Generally speaking, during the ovulation period, the body temperature will increase by 0.3-0.5 degrees Celsius.

2. Observe symptoms: During the ovulation period, women may experience symptoms such as increased sexual desire, breast swelling, changes in appetite, dizziness, and fatigue. These symptoms usually appear a few days before ovulation and last for a few days.

3. Use a calendar: Using a calendar can help women determine when they are ovulating. Mark a woman's menstrual cycle on a calendar and record the days of each month. Generally speaking, in a woman’s menstrual cycle, ovulation usually occurs on the 14th day.

4. Observe changes in body temperature: Women can determine their ovulation period by measuring their body temperature. Take your oral or anal temperature every morning when you wake up and record changes in body temperature. Generally speaking, during the ovulation period, the body temperature will increase by 0.3-0.5 degrees Celsius.

These methods can help women better understand their bodies and make it easier to get pregnant during ovulation. If you are not pregnant yet, it is recommended to consult with your doctor to learn more about pregnancy and childbirth.
