Four days after menstruation, coffee colored blood appears when you go to the toilet

Hello! Women's menstrual period is generally 3 to 7 days. The pattern of menstruation is that there is not much menstrual blood on the first day, more on the second and third days, and then gradually decreases until the menstrual blood is clean.

This is because the shedding of the endometrium has just begun on the first day, and the shedding of the endometrium on the second and third days increases, the amount of bleeding also increases, and the uterus is stimulated, which strengthens the contraction and discharges a large amount of menstrual blood. After some people's menstrual blood is cleaned, a little bit comes after a day or two, commonly known as "menstrual blood back", which is also a normal phenomenon. Best wishes!

It's best to go to the hospital to see it, try it is the reflux of menstruation, if you want to have a child, you have to pay attention to it, I wish you health!
