The number of days of menstrual bleeding in women is usually around 2~8 days. The endometrial stripping will be reduced when menstruation is about to leave, and the amount of menstrual blood will gradually decrease at this time, and the blood will be discharged in a darker color as it has been accumulated in the uterus for a longer period of time. During menstruation, there are symptoms such as menstrual cramps and chest pain, which will gradually disappear with the end of menstruation, and you will be able to tell that it’s time for your period to go away. Every woman’s body is different, some women already have these symptoms of menstruation, but due to abnormalities in the body, such as dysfunctional uterine bleeding and fibroids, the number of days of menstruation may be prolonged, and it will be more difficult to determine when the period is completely clean. Women are advised to observe their menstrual flow more often and seek medical attention if there is any abnormality.
