How often do menstruation occur?

As women, we experience a menstrual period every month, but because each person's situation is different, the number of menstruation is also different. So how often is menstruation normal? Some people may have their period once a month or every two or three months. Normally, menstruation should come every month, but some people's periods are so abnormal that it is alarming, which causes us a lot of trouble. How many days of menstruation is normal? I believe this is a question that everyone is concerned about.

Most common: menstrual cycle 21-35 days

"I only have my period once every two months. My boyfriend said that it must be abnormal. What medicine can help me adjust my menstrual cycle to normal?" Xiaolin, with a distressed look on her face, turned to the gynecologist for help. But the doctor ruthlessly discouraged her from doing so. "Your menstruation is basically maintained every two months, and you don't have any related diseases. This is normal and does not require treatment. It is not recommended to take medicine to regulate menstruation."

It turns out that the phenomenon of "menstruation" once every two months, once every three months, or even once every six months or a year not only exists, but also this seemingly "abnormal" menstrual cycle may not be abnormal! Experts and professors say that Western medicine calls "menstruation" vaginal bleeding caused by the shedding of the endometrium, while Chinese medicine calls "menstruation" vaginal bleeding that occurs on schedule every month and repeats over and over again. "But this can only describe the situation of most people. Some people have different cycles." Experts say that the most common menstrual cycle is 28 days, and ±7 days before and after is considered within the normal range, which means that 21 to 35 days is the most common normal menstrual cycle. "Moreover, the calculation method of the menstrual cycle should not be based on the natural month, but from the first day of this menstruation to the first day of the next menstruation." Experts say that according to this calculation, some people have a period at the beginning of a natural month and a period at the end of the month. As long as the interval between the two periods is 21 to 35 days, it is normal.

In addition to menstruation, there are also combined menstruation and quarterly menstruation.

Don’t compare your menstrual cycle with others, but compare it with yourself. "The length of the menstrual cycle varies, and the key to judging whether it is normal is to see whether a long-term pattern has been formed. If it has been like this for one or two years, the estrogen level in the body is normal, ovulation is normal, and there are no other discomforts, then it is normal." Experts point out that in addition to menstruation that occurs every 21 to 35 days and menstruation during menstrual amenorrhea, pregnancy, menopause, and early puberty, there is also a special type of normal menstruation, which occurs every 40 to 50 days, or once every two months, or once every three months, or even once a year. As long as a regular pattern is formed and there is no physical discomfort, it is normal.

"In traditional Chinese medicine, menstruation that occurs every two months is called 'bingyue', menstruation that occurs every three months is called 'jijing', and menstruation that occurs once a year is called 'bi nian'. There is no special name for menstruation that occurs every 40 to 50 days in traditional Chinese medicine, but it is very common for women to have this menstrual pattern." Experts said that there is another special condition called "dark menstruation" that has not been seen in the outpatient clinic but has been introduced in traditional medical books. People with dark menstruation will never have menstruation throughout their lives, but they will have ovulation and reproductive functions, and they are also normal people.

Why do women have such different menstrual cycles? Experts explain that Western medicine believes that this is related to the length of time it takes for the ovarian follicles to develop. People whose follicles develop for a long time have longer menstrual cycles. A menstrual cycle is divided into the menstrual phase, follicular phase, ovulation phase and luteal phase. At the same time, the endometrium goes through a process of cyclical thickening and congestion, from stripping and bleeding to gradual thickening and congestion. However, this process takes longer for some people and less time for others, resulting in some people having a longer menstrual cycle and some people having a shorter one.

The editor has summarized the relevant knowledge about normal menstruation above. After reading the above article, I believe everyone should have understood it more or less. Therefore, everyone must keep a record of their menstrual period so that they can make a targeted and reasonable analysis of their menstrual period and then determine whether their menstruation is normal or not.
