I would contact the on call doc and see what they say.
Iam goin throuvh tjis now..im always constipated even before being prsgnant.lol..but for like 5 days now ive been going through the same as you however mine isnt mild its pretty bad
I had the same problem around the same time, I even went to the hospital freaking out, they said it was normal and sent me home. I believe you're fine. I was. But if you still don't feel right, or feel like something is wrong, call your doctor! Trust your instinct. I always do. If I feel something is wrong I ask a million people and still end up going and making sure lol. C:
If you have diarrhea that means your body needs fluids. Dehydration will make cramp terribly!
It could be a bug or something you ate completely unrelated to pregnancy. Drink extra fluid so you don't get dehydrated.
