I am 9 weeks 3 days today and had not thrown up once this pregnancy until last night! And holy crap I could not stop. I was feeling completely horrible and getting up to vomit every single hour and had diarrhea bad around 4 am. I'm currently in bed nauseous as all get out and feeling weak, I know I need to get up and try to eat something I'm just afraid to after what I experienced all night.
