Ovulation refers to the time when a woman ovulates, usually around day 14 of her menstrual cycle. On this day, a woman's ovary will release a mature egg, which will then survive in the body for 2-3 days. If the egg is fertilized, the woman becomes pregnant.

Measuring basal body temperature is a simple and effective method. Every morning when you wake up without getting out of bed, take your oral temperature. Record it and compare it after the cycle is over. Generally speaking, a woman's basal body temperature will increase by 0.3-0.5 degrees during ovulation.

Watching symptoms can also help determine when you are ovulating. For example, symptoms such as abdominal pain on one side, breast tenderness, nausea, and vomiting may occur. These symptoms usually appear around ovulation and can help women better determine whether they are ovulating.

Although measuring basal body temperature and observing symptoms are simple and effective ways to determine ovulation, it is not suitable for everyone. For some people, these methods may not be accurate enough. Therefore, if you are not sure how to determine ovulation, it is best to seek advice from your doctor or other professionals.
