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 further during ovulation, then gradually rises afterward.
3. The menstrual cycle calculation method. Many women do not know exactly when their ovulation period is, but by using the following formula and testing for a period of time, it can be easily calculated.
The calculation formula is:
- First day of ovulation period: Cycle days minus 18 days
- Last day of ovulation period: Cycle days minus 11 days
