I am 12 weeks pregnant, and I have been having diarrhea for the past 3-4 days. Sorry if TMI, but I am going to the bathroom around 3x/day. I have always had a bad stomach so I wasn't too alarmed, but am starting to get worried. I was just at my OBs office and my baby is doing great (forgot to mention this b/c I thought it was no big deal). I have also not gained any weight btwn week 8 and 12, and I am eating 3 meals a day plus snacks.I feel like food goes right through me. Should I be concerned?
