Contractions

I'm sure these contractions are caused from dehydration. Ugh its so hard to drink. I've been trying to suck down more water but I'm still having them. I don't think they're Braxton hicks. They're kinda strong and have been going on for a few days now. Can dehydration put me into preterm labor? I don't want that to happen. How can I get more liquids down when I just want to puke? Anyone else having contractions due to not drinking enough?
