The day before menstruation is the ovulation period

So, when is the day before menstruation? In fact, the day before menstruation marks a woman's ovulation period. During this period, a woman's egg has been waiting for approximately 8 days to fertilize with sperm. Therefore, if you want to get pregnant, the day before menstruation is the best time for fertilization.

A woman's menstrual cycle can be affected by many factors, including genetics, hormonal levels and lifestyle. Therefore, everyone's cycle is unique, and not all women will ovulate the day before their period. However, if you want to know your cycle and ovulation, the best way is to measure your basal body temperature and observe your menstrual cycle.

Measuring basal body temperature can help women determine when they are ovulating. At the beginning of the cycle, a woman's basal body temperature will be relatively low, then gradually increase until it reaches a peak and remains there for a period of time. If women measure their basal body temperature the day before menstruation, their body temperature will peak on this day, and their body temperature will remain high for several days within this day.
