The method of determining when you are ovulating may vary from person to person, but here are some common methods:

2. Measure body temperature: Measuring basal body temperature can help determine your ovulation period. During ovulation, body temperature usually rises by 0.3-0.5 degrees Celsius as the body prepares for pregnancy.

3. Use a pregnancy test: A pregnancy test is a simple way to help test whether you are pregnant. It is possible to get accurate results using a pregnancy test on the 14th day after ovulation.

4. Observe the menstrual cycle: Usually, for women with normal menstrual cycles, the ovulation period is about 14 days before the next menstruation. Therefore, if the menstrual cycle is 28 days, then ovulation may be around the 10th.
