I had a miscarriage so saying don't worry almost makes me laugh, I know women inherintly worry about their babies. Anyhow, I am only about 2 weeks pregnant and I kinda have diarea (sorry, I can't spell). My aunt in law was so sick for the first 15 weeks of her first 2 pregnancies that she was in the hospital with a feeding tube and she has 2 beautiful little boys, perfectly health! If you can't stop vomiting or cannot control your bowels go to the hospital but vomiting and diarea are very very very common
