urgent ! am I having preterm labor pains

I'm 29 weeks and I have these small cramp pains sometimes they make me cringe but nothing that I can't handle. They just started about and hour ago ... I'm just laying down watching a movie nothing to big and they started as a stomach ache but now more like small period cramps..It's 12:30a and I don't know what I should do I'm a first time mom so I don't know if this is normal such as Braxton hicks or should I wait to see if they progress in a couple of days.
