Contractions

Champayne
I'm having contractions but they don't really hurt. I'm 38 weeks and been having contractions often. The only thing is they don't hurt so I don't know if it's real or not. My whole stomach gets super tight for a good 30 seconds to a minute and then the next comes not that far after. Should I call my doctor or just wait it out until they get closer and my water breaks? 
Ps. I went to the doctors on Monday and she said the baby can come any day now. I just don't want to go in to be released a little later.
