Tmi, I'm 4 weeks pp tomorrow, the last whole week the bleeding slowed down to literally nothing just like barely pinkish/orangish tint, then today I'm bleeding quite a little bit and bright red? No cramping like I'm on my period or anything though? Normal? Could it be my period already without any cramping? Just think it's strange I've literally went a week with no discharge besides a tiny TINY pink tint when wiping and now it's back kind of like I got my period but not that heavy. Thanks
