Ovulation refers to the period when hormone levels are highest in a woman’s body and is also an important period for women to become pregnant. Normally, a woman's ovulation occurs on the 14th day before her next menstrual period. However, due to the different physiological conditions of each person, the specific ovulation period is also different.

1. Record menstrual cycles: Women need to record their menstrual cycles in order to determine the date of their next menstruation.

2. Calculate the ovulation period: Women need to count from the first day of their next menstruation, and the 14 days to the end is the ovulation period.

3. Observe symptoms: Women may experience these symptoms during ovulation, such as changes in appetite, increased energy, breast swelling, increased secretions, etc.

4. Use test strips: Women can use test strips to test their ovulation period to determine whether they are in a dangerous period.

To sum up, a woman’s ovulation period is a relatively fixed period, but in order to ensure pregnancy, women need to follow the above steps and pay close attention to their symptoms and physical condition.
