Hello, brownish vaginal discharge at the end of menstruation is a normal phenomenon. This occurs because, at this stage, only a small amount of endometrial tissue is shed, resulting in minimal bleeding. The blood remains in the uterine cavity and vagina for a prolonged period and becomes oxidized, turning brown. When mixed with normal vaginal secretions, it appears as brownish discharge. I hope this information is helpful to you. Wishing you good health!
