I have this really weird rash all over my stomach and chest. It started out in the middle of my stomach last night and now it's all over my boobs, sides, chest and stomach. It doesn't itch or burn or anything just there. Any other mommies gone through this? I haven't ate anything new or been on any new medications so I have no clue 😩
