The period before menstruation is ovulation

However, not every woman will experience ovulation in every cycle, depending on their physiology and the length of their menstrual cycle. Therefore, for some women, their menstrual cycles may be longer or shorter, causing their ovulation periods to differ.

So, what is menstruation? Menstruation refers to the time when a woman's eggs are released from the ovaries into the fallopian tubes, usually starting on the 14th day of the menstrual cycle and continuing until the 16th day. During this process, a woman's eggs are continuously formed in her ovaries and then expelled from the body through drainage pipes.

So, how to predict ovulation? Generally speaking, women can predict ovulation by:

1. Observe the menstrual cycle: Observe a woman’s menstrual cycle to understand the number of days and length of each month.

2. Measure basal body temperature: Women can predict ovulation by measuring basal body temperature. When women wake up every morning, they get up and take their temperature, and then record changes in body temperature.

3. Use a pregnancy test stick: Women can use a pregnancy test stick to test whether fertilization has occurred. Pregnancy tests usually have two lines, one indicating no fertilization and the other indicating fertilization.

4. Observe appetite: During ovulation, women may feel an increase in appetite, which may be due to the egg needing enough nutrients to implant.

5. Watch for symptoms: Some women may experience uncomfortable symptoms such as fatigue, breast swelling, headaches and nausea.

The above methods cannot completely accurately predict a woman's ovulation period. Therefore, women need to combine their physiological conditions and menstrual cycles and consider multiple factors to predict their ovulation period.

Finally, I would like to remind women that during the dangerous period, women need to protect themselves and avoid unnecessary risks. At the same time, women should also pay attention to their physical health and undergo regular physical examinations and health care.
