Normal Menstrual Cycle
The normal menstrual cycle can be different for every woman. A usual period often happens about every 4 weeks and lasts around 5 days. During this time, you might lose between 30 and 40 milliliters of blood. Variation in the duration and amount of blood loss during a menstrual cycle is not as medically significant as other symptoms like discharge, pain, or bleeding. Some other forms of abnormal uterine bleeding include bleeding after menopause, bleeding during periods, and too-frequent menstrual cycles. Vaginal bleeding can be a concern for people when it happens after the menopause, around 50 years old. [2]
