Doctor's answer:

Here is the English translation of the provided content, with the carriage returns remaining unchanged and all other Chinese text translated into English:
1. The cervical mucus method: In the gynecology department of a hospital, cervical mucus is examined to determine if a woman is in her ovulation period.
2. The basal body temperature method: Measure your temperature every morning after waking up. Generally, your temperature is lower in the first half of the day and drops even further during ovulation, then gradually rises afterward.
3. The menstrual cycle calculation method. Many women do not know exactly when their ovulation period occurs. Using the formula below, after some testing over time, it is easy to calculate.
The calculation formula is as follows:
- First day of ovulation period: Cycle days minus 18
- Last day of ovulation period: Cycle days minus 11
