Ovulation refers to the time when eggs are released from a woman’s body and is also an important period for women to conceive a fetus. If you want to know if you're past ovulation, here are some ways:

2. Measure body temperature: A woman’s body temperature will rise during certain periods, especially during ovulation. This period can be monitored by recording body temperature.

3. Observe basal body temperature: Basal body temperature refers to a woman’s body temperature when she is awake. Women’s ovulation period can be monitored by recording basal body temperature.

4. Use a pregnancy test stick: If you have missed your ovulation period but still want to confirm whether you are pregnant, you can use a pregnancy test stick.

5. Check your blood: If you've postponed your appointment, you can check your blood for HCG levels to determine if you're pregnant.

If you miss your ovulation period, don't worry too much. If you still want to have a baby, you can wait a while or take other methods to get pregnant. If you are pregnant, take regular care of yourself and your baby to ensure their health.
