The ovulation period refers to the days in a woman’s menstrual cycle when her body temperature is highest and when hormone levels are highest in her body. For couples trying to have a baby, knowing your ovulation period is important because it determines when embryo implantation can begin, ensuring a healthy baby.

1. Measure basal body temperature: When women wake up every morning, measure their oral body temperature (oral measurement method). Record the measured body temperature on a table and record it on different days during the cycle.

2. Observe the menstrual cycle: Observe the woman’s menstrual cycle and record it in the table. Cycle days usually refer to the time from the beginning of basal body temperature measurement to the start of the next cycle.

3. Determine the date with the highest body temperature: By recording the basal body temperature, the date with the highest body temperature can be determined. In the days surrounding this date, a woman's body temperature will rise, which is a sign of ovulation.

4. Observe symptoms: During ovulation, women may feel fatigue, breast swelling, increased sexual desire, etc. These symptoms may appear a few days before and after ovulation.

Through the above methods, a woman's ovulation period can be accurately calculated. During ovulation, a woman should take a pregnancy test, but it\'s not necessary to take a pregnancy test right away. It\'s recommended to wait at least 7 days after the highest day of body temperature to take a pregnancy test.

A woman's ovulation period is a relatively fixed date, not a specific number of days. Therefore, couples do not need to measure their body temperature every day, but should observe the menstrual cycle and symptoms, determine the day when the body temperature is the highest, and perform embryo implantation during the possible period.
