Can contraction-like pain be from not drinking enough water?

BuckeyeWife07

For the past hour or so I've had some really sharp pains, that wrap from my back around. I don't think they are real contractions since the baby is still moving plenty and the top of my stomach isn't getting that hard (thank God). Could I be getting these from not drinking enough water? I've only had a couple bottles worth today, which I know isn't too smart.. but I'm too nauseous to drink it very fast. Yes, this is my second, so I probably sound dumb, but I'm trying to figure out if I should be worried at all. Relaxing tonight really isn't an option since I'm about to go pick up my toddler and be home alone with her for the evening.
