hi, I have a 7 week old baby, and a week after he was born I was rushed back to the hospital for severe hemorrhaging from post partum endometritis, after a week of recovering I had my first period after the baby, and now last week I started birth control, I had stopped after 3 days due to extreme cramping and bloating, now this week I have heavy bleeding, bright red blood, and don't know if its endometritis or another period due to stopping birth control
