The ovulation period refers to the release of eggs from a woman's ovaries within a few days of each month, which is crucial for fertility. Although most people don’t know the exact days of ovulation, scientific research shows that women will ovulate in the middle of each month, that is, around 14 days.

Therefore, the exact time of ovulation varies from person to person. For some people, ovulation may only last a few days, while for others it may last several weeks. However, regardless of the duration of ovulation, it is crucial for fertility.

If you want to get pregnant, it's best to accurately calculate your ovulation period and have as much sexual intercourse as possible during this period. Doing this improves sperm quantity and quality, thereby increasing your chances of pregnancy.

If you're not sure about your menstrual cycle or don't know the exact day of ovulation, it's best to consult your doctor or a professional fertility counselor. They can help calculate and guide you to have intercourse during this time to increase your chances of pregnancy.
