Braxton hicks or contractions?

It's been 7 years since I had my daughter and I didn't realize I was having contractions until my water broke and I was like "oh that's that pain I kept getting every few minutes" (mind you I was 16, no idea what was going on) so this time around with my second I am 32 weeks and 4 days and at about 10pm I felt a little pain under my right if belly and again every 30 minutes since then... It's been 2 1/2 hours now, they aren't getting closer or stronger so in guessing it's Braxton hicks but what do you ladies think?
