As a woman, when reaching the childbearing age, there will be a few days when she will have difficulty moving around, and she will also experience symptoms such as irritability and abdominal pain in her mood, indicating that she is in the menstrual period. Menstruation is a normal physiological phenomenon in women, and it also has a certain cycle. Is a menstrual cycle of 21 days normal?
The typical menstrual cycle is 12-35 days, with an average of 28 days. Usually, each cycle lasts for 2-7 days, with an average of 4-6 days. Moreover, the total blood loss during a menstrual cycle is considered normal at around 30 to 50ml. If the menstrual flow is normal and there are no other abnormal symptoms, then a menstrual cycle of 212 days is also considered normal.
Menstruation is a physiological manifestation produced by the female body, mainly referring to the periodic shedding and bleeding of the endometrium caused by the periodic changes in the ovaries. Therefore, this physiological manifestation has a certain periodicity. However, due to differences in women's physical constitution and lifestyle habits, there may also be delays or advances during menstruation.
It is normal for women to delay or advance their menstrual cycle by one week depending on their own situation. However, if the menstrual cycle is delayed or advanced by ten days, it is necessary to go to the hospital for gynecological examination in a timely manner to avoid menstrual disorders and abnormal physical manifestations, which may even lead to gynecological diseases in women.
