stomach bug while pregnant.

I'm 19 weeks, and my 2 year old daughter passed on the worst stomach bug know to man to me. I can't keep anything down! I'm starving, but afraid to eat anything because I cry every time it comes back up due to sore stomach muscles! I can keep some water down, but if I eat anything, it reappears in an hour or two! Pretty sure I'm dying. I've tried saltines, ginger ale, and sparkling water. What remedies would you try in this situation?
