After your period is over, you have dark brown again. The first thing to look for is a dark brown discharge a few days after the end of your period. Normally, leucorrhea should be clear, transparent, odorless, and in small amounts. This dark brown color is mainly because there is bloody discharge among the leucorrhea secretions. A small amount of blood, which stays in the vagina for a long time, will result in a dark brown discharge. It is not normal for dark brown to appear after menstruation. The appearance of dark brown color during ovulation indicates low estrogen in the body during ovulation. Usually the amount is small and can go back in 2 or 3 days, which is normal. If you have dark brown discharge during intercourse after menstruation, you must go to the hospital to see the cervix at this time. If there is a problem with the cervix, there will be contact bleeding and cervical cancer and precancerous lesions must be ruled out. If there is no such disease, it is simply caused by inflammation of the cervix.
