I am almost 7 weeks postpartum and started bleeding again a few days ago. It's not heavy, and sort of a pinkish color. I'm not even wearing a pad, it's mostly just when I wipe. I am seeing the doctor this week, but I was wondering if anyone else experienced this and what was the cause? I am exclusively breastfeeding, so I doubt it's my period (also not heavy enough to be a period). I had a vaginal birth without complications. I did have sex for the first time last Sunday, and the bleeding started a day after that, so I wonder if that has something to do with it.
