Doctor's answer:

Here is the English translation of the provided content, with line breaks retained as instructed and all Chinese text translated into English:
1. Cervical Mucus Method: In the gynecology department of a hospital, this method involves examining cervical mucus to determine if you are in your ovulation period.
2. 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 further during ovulation, then gradually rises afterward.
3. Cycle Counting Method: Many women do not know exactly when they ovulate. Using the formula below, after some testing over time, it is easy to calculate.
- First day of ovulation period: Cycle days minus 18 days
- Last day of ovulation period: Cycle days minus 11 days
