The ovulation period refers to the time when a woman's eggs are released from the ovaries to the fallopian tubes. It is also an important period for women to become pregnant. For many women, knowing when they are ovulating can help them better plan their pregnancy and stay healthy.

We can estimate a woman’s ovulation period as follows:

1. Observe the menstrual cycle: If a woman’s menstrual cycle is 28 days, then observation starts from the 14th day of the menstrual cycle and ends on the 21st day of the menstrual cycle. During this time, a woman's eggs begin to mature and are gradually released.

2. Measure body temperature: Women can determine their ovulation period by measuring their basal body temperature. When you wake up every morning, measure your oral or anal body temperature and record changes in body temperature. Generally speaking, in a woman's menstrual cycle, the day when her body temperature is lowest is her ovulation period.

3. Use an egg test kit: Some women can use an egg test kit to determine when they are ovulating. These tools measure the number and quality of eggs in a woman's ovaries to determine when she is ovulating.

No matter which method you use, knowing when a woman is ovulating can help her better plan for pregnancy and stay healthy. If a woman wants to get pregnant, it's best to have sex during ovulation to ensure sperm and egg meet. At the same time, women should also maintain good eating habits and moderate exercise to ensure their physical health.
