How many days does the menstrual cycle last?

Only those who don't know or understand their own physical condition will not know how many days their menstrual cycle is, or only some men who don't understand the situation will have such problems. In fact, menstruation is women's menstruation, which is a regular process of menstrual blood being discharged from the body. Basically, a normal female menstrual cycle is five days, and some last seven days. The abnormal ones will be less.

Normal menstruation for women occurs every 28 to 30 days (may also fluctuate by 3 to 5 days), and the menstrual period lasts for 3 to 5 days (may also fluctuate by 2 days). Regular ovarian ovulation is the fundamental guarantee for normal menstruation. Women have two ovaries, one on each side, located behind and below the fallopian tubes on both sides of the uterus. They produce eggs and sex hormones to maintain women's normal menstrual physiology and reproductive function. In a mature female, generally one follicle matures and releases a mature egg every month. Ovulation usually occurs in the middle of two menstrual periods, roughly about 14 days before the onset of menstruation.

Under the direct action of ovarian hormones, the functional layer of the endometrium in the fundus and body of the adult endometrium undergoes periodic changes. Endometrial exfoliation, bleeding, repair, and proliferation occur approximately every 28 days, a process called the menstrual cycle. The cycle is divided into the proliferative phase, the secretory phase and the menstrual phase. The proliferative phase is equivalent to the follicular phase of the ovarian cycle. The proliferative phase can be divided into early, middle and late proliferative phases according to the changes in the endometrium. The secretory phase occurs after ovulation, also known as the luteal phase. The secretory phase can also be divided into early, middle and late secretory phases. The end of the secretory phase and the onset of menstruation are called the menstrual phase. The menstrual cycle is from the first day of menstruation to the day before the next menstruation. In a typical 28-day cycle, there are 14 days before ovarian ovulation. Days 1 to 4 are the menstrual period, days 5 to 7 are the early hyperplasia period, days 8 to 10 are the middle hyperplasia period, and days 11 to 14 are the late hyperplasia period. After ovulation, the 15th to 18th days are the early secretion phase, the 19th to 23rd days are the middle secretion phase, and the 24th to 28th days are the late secretion phase.

Finally, women have their periods about once a month. If they are in good physical condition, their periods will be more regular. The normal menstrual cycle is 28 days on average. Some people have more and some have less. Women should pay attention to not eating cold food or ice cream before their periods come. They should take good care of their bodies. I wish you a happy life.
