I have my period on the 23rd, so my next period should be around April 28th. Based on the 28-day menstrual cycle, the ovulation period should be 7 days after the end of menstruation on the 23rd of next month. During this period, a woman's eggs are released from the ovaries and travel into the fallopian tubes to await fertilization.

1. Keep track of your cycles. Recording begins on the first day of menstruation and is recorded every 7 days. In this way, you can know your menstrual cycle and the date of your next period, and calculate your ovulation period.

2. Observe changes in your body. During ovulation, a woman's body may experience some changes, such as increased body temperature, increased appetite, and breast swelling. These changes can help you better understand the period.

3. Use a pregnancy test stick or kit. If you want to determine whether fertilization has occurred, you can use a pregnancy test or kit. These tools can help test for the presence of embryonic tissue.
