How long is the menstrual cycle? You must read the correct method to calculate the menstrual period

If you are a normal woman of childbearing age, your menstrual cycle usually ranges from 21 to 35 days. As long as your menstrual cycle is regular, it is normal to have your period three days earlier or later than usual. As long as the color and volume of your menstrual blood are normal, you have a regular menstrual cycle.

Menstruation is a necessary stage for every woman. The menstrual cycle is not fixed, but it has a general range. If it is obviously beyond the range of the menstrual cycle or the menstrual cycle is irregular, it is likely that there is something wrong with the body. So what is the range of the menstrual cycle?
1. What is the range of menstrual cycle ? Normal menstrual cycle of women of childbearing age ranges from 21 days to 35 days, with an average of about 28 days. If the menstrual cycle is less than 21 days, it can be defined as frequent menstruation, and if the menstrual cycle exceeds 35 days, it is oligomenorrhea. However, as long as the menstrual cycle is regular, it is normal to be three days earlier or three days later than the original. As long as the color and amount of menstruation have not changed, it is a regular cycle and there is no need to worry too much.
2. Reasons for abnormal menstrual cycle range
1. Reasons for short menstrual cycle <br/>If you have just started menstruation or are in menopause, it is normal for your menstrual cycle to be too short. But if you are a normal woman of childbearing age, a short menstrual cycle may be caused by certain gynecological diseases, such as premature ovarian failure or uterine adhesions. It may also be caused by endocrine disorders caused by external factors.
2. Reasons for prolonged menstrual cycle <br/>This situation is related to infection of reproductive organs. If the uterus suffers from certain diseases, such as endometriosis or uterine tumors, it may also cause the menstrual cycle to be too long. In addition, if you have a blood disease or wear an IUD, the menstrual cycle will change, mainly manifested as a prolonged menstrual cycle.
