i had that with my son. i was 36 weeks and i was vomitting and having diaherra so bad that my contractions were right on top of each other and had to get fluids pumped into me.

My sister in law was so sick her entire pregnancy she was in the hospital like every other week because she couldnt keep anything down and they were having to give her bags of fluid. but then again she had a gallbladder problem. The doctors actually didnt find it, it was an ultrasound tech that was friend of her moms.

Some ppl just get it worse than others, and youll get thru it and have a beautiful baby at the end. How far are you? I would get a second opinion on the gallbladder just in case.
