So they found pieces of my placenta still in me and that's where the extreme cramps were coming from. Tomorrow I get a D&C to take them out, They gave me Hibiclens to clean up tonight and tomorrow before the surgery. And I was wondering if it was safe to clean down there with it since my stitches are still there from having my son last Saturday? I got second degree stitches.
