Can you keep down water/broth/soda/liquids? My only concern would be if you think you've lost so much fluid that you're at risk for being dehydrated. Dehydration can cause you to have more contraction activity (not that you'd be sent into full-blown labor, but it's sort of a sign from your body that you need more fluids). If you start feeling really out of it, you always have the option to go get a bolus of saline intraveneously. I wouldn't be too worried right now as it's only been a day or so, but do try to drink some fluids, even little sips.
