okay- postpartum question. When I had my 6 week checkup my OBGYN didn't check my stitches or anything. I was under the assumption he'd check just to make sure everything healed properly but he didn't. Well at 4 weeks postpartum I stopped bleeding completely. I had heavy white discharge which I was told was a sign my body was gearing up to ovulate. well yesterday I had light light light pink spotting, (I've never EVER spotted before, except for during pregnancy- but never during periods) and today I have brown discharge. is this normal or cause for alarm? Anyone else have this?
