Worried !! (Preterm Labour?)

So all day I've been having Braxton hicks (at least I think they are). I've also been getting these sharp shorting pains up my back and pelvis. I'm very crampy, which may also be the bh's. But I also have a lot of pressure going on and of course the tightning of the contractions. I took a bath, got some rest, drank some water, and just now threw up violently. Should I go to the er ? Or wait until my appointment Wednesday.
