It is considered normal for your period to end in 8 days, if it does so every time. Because menstruation comes in 2-8 days and the average is in 3-7 days, it is considered a normal cycle if it ends within 8 days every time. It is important to observe if there is any abnormal bleeding during the non-menstrual period without a period, and if there is any abnormal bleeding for more than 8 days, because the presence of adverse reactions can cause gynecological diseases and even endocrine hormone problems. If you are not sure, you can also go to the hospital for an ultrasound examination 3 days after your period to determine if there are any abnormalities in the shape of the uterine cavity, inflammation or fluid in the pelvis. These factors can cause the 8 days of menstruation and can also be treated with medication according to the situation.
