I'm 18 weeks postpartum with emergency c/s and placental abruption. Bleeding for 15 weeks post birth and brown discharge last 3 weeks. Please can you?

Emergent C-section. Placental abuption may result in retained fragments of placenta still in the uterus, which can cause continued post partum bleeding. See your OB provider, who may recommend a "D&C" to remove additional tissue which should stop the bleeding. Some of the bleeding at this point might be coming from a natural "period" .
