Menstruation and ovulation

Menstruation refers to a woman’s menstrual period every month, which usually lasts about 3-7 days. During menstruation, a woman has bleeding from her vagina, which is usually red or pink in color. This is caused by the shedding and expulsion of the lining of the uterus. After your period, a woman's vaginal bleeding will stop.

Ovulation refers to the 14 days after menstruation, which is the 15th day of a woman's menstrual cycle. During this period, there are a large number of egg cells in the female vagina, and these egg cells are waiting to be fertilized by sperm.

The process of egg maturation and expulsion takes 14 days. During these 14 days, there are a large number of egg cells in the female vagina, and these egg cells are waiting to be fertilized by sperm. This period is also known as the "danger period" or "fertile period" for women.

In addition to menstruation and ovulation, a woman's menstrual cycle is affected by many factors, such as age, hormone levels, diet and exercise. Therefore, a woman's menstrual cycle may vary.

Menstruation and ovulation play an important role in women's health and fertility. Understanding these menstrual cycles can help women better manage their physical health and promote fertility. If you have any questions or discomfort, please consult your doctor.
