Disease description:

Generally, we may experience a small amount of brown discharge two days after menstruation. This discharge mainly occurs because there is still a small amount of stagnant blood remaining in the uterine cavity. Then, what does it mean when a 12-year-old girl has blackish-brown menstrual blood?
