Im 10 weeks pregnant and have mild diarhee with stomache cramps is it harmfull?

Pregnant or not,...: Loose stools can be from variety of causes, generally without affecting the pregnancy. People usually see their doctors if symptoms are bad or if they last more than 2 days. When diarrhea first begins, a person can benefit by stopping oral intake for a few hours, and then start just drinking small amounts (few ounces) of something like Pedialyte or half-strength Gatorade each hour for a day.
