I had diarrhea throughout most of the first tri. It is now less diarrhea and still soft stools and I have more than one BM a day still. It's NORMAL (have heard of other ladies with this, it's not common per se, but not unheard of) and won't affect bubs. Just be sure you are drinking a lot of water as diarrhea can make you dehydrated. I wasn't worried as I was drinking jugs and jugs as I was very thirsty.
