My doctor told me it's normal it's just as common as morning sickness, and constipation, it's just not as popular, it can be from the increasing hormones or adjusting to prenatals, if it continues, make sure you bring it up to your OB though!
I just typed in "Is it normal to have an upset stomach and diarrhea during pregnancy?"
Omg it did it again. I found it on yahoo answers.
Ok I dont know why it put stars but its ***************** then the rest
Heres the link to one of the forums I read about that. http://*****************/question/index?qid=20091213162958AA3vtpF
Im not to sure where but I read online that diarrhea with or without an upset stomach is normal for some women. It said just to make sure and stay hydrated. And that it could be what ur eating. Ill look now and see where I read it then ill post the link.
