Hmm. Labor?

I went to the hospital due to contractions and clear fluid. I was having contractions 3-4 minutes apart. They did a strip test and it showed that it's negative, my water hasn't broken. But when I stand up, I feel extremely "wet"..
Anyways, they've sent me home and said I'm supposed to take Benadryl every 6 hours. I'm dilated to a 3 and 50% effaced. I'm 35w4d. 
What does this mean?
