Ovulation is a few days before the next menstrual period

To determine ovulation, you need to know a woman's menstrual cycle and fertility. Typically, a woman's menstrual cycle lasts 28 days, but some people have longer or shorter menstrual cycles. Fertility depends on many factors, including age, health and lifestyle.

During a woman's menstrual cycle, a mature egg is released from the ovary and waits for fertilization in the ovary. Under normal circumstances, it takes 6-8 hours after the egg is released to reach the fallopian tube, where it waits for fertilization.

According to scientists' research, in a woman's menstrual cycle, ovulation usually occurs about 14 days before the next menstruation. This is because a woman's menstrual cycle is affected by many factors, including the function of the ovaries and fallopian tubes, the environment of the uterus and vagina, etc. These factors all affect women's fertility, and ovulation is one of the effects of these factors.

Although calculating ovulation can help women predict when they will fertilize, not every woman can accurately calculate her own ovulation. Some women may be affected by other factors, such as mood swings, weight changes, and exercise.

Therefore, women do not have to worry too much about the calculated ovulation period. As long as they maintain a good lifestyle and health, it is possible to realize their fertility dreams.
