In general, a normal menstrual period lasts 2-8 days and can end in no more than 8 days. A woman’s menstruation is cyclical, and a normal menstrual cycle is usually 21-35 days, with an average of 28 days, and each period lasts 2-8 days, ending in 4-6 days on average. The amount of menstruation is about 20ml-60ml, and more than 80ml is called increased menstruation. In addition, because there will be hormonal changes with each menstrual period, female patients will have some abdominal discomfort or even dysmenorrhea, so they can pay more attention to rest and observation. If there are obvious menstrual abnormalities, then it is recommended to consult a hospital in time to avoid delay.
