Can contractions just go away?

I've been increasingly, over the passed few days, getting more contractions more often. I'm now getting them like 1-2 an hour. Like bad period/diarrhea cramps and tightening. I feel nauseous and hot and just overall like crap. I'm not due until Nov 24th. So is it possible they could just trickle off and stop? Or is this likely to continue for possibly the next couple weeks?! I'll go nuts if this goes on for days to even a week.
