What Can I Eat (FTM)

I'm a FTM and lately I've had tons of trouble eating. I'm about 11 weeks 2 days along. I've tried fruits and a little bit of everything but I just throw it up. I use to be able to get away with soups, but now I'm throwing that up too. I haven't had water in 2 days because even if I drink water I'm throwing that up. It's gotten to the point where my stomach hurts because I'm heaving and there's nothing left for my body to throw up. I'm really hungry and thirsty but can't keep anything down, I've even tried peanuts. Should I go to the hospital? I'm worried about the baby.
