Contractions?

Tristan

So the past hour Ive been having these contractions every 10-15 minutes that feel like I have horrible gas. It starts out as a mild cramp and then increases really painfully for about 10 seconds before fading away and the urge to pass gas is gone too. I thought at first I just had to use the bathroom but everytime i have a contraction i try and nothing happens lol. Is this what real contractions feel like? My mom said hers felt like this later on when she was about to push but I cant tell if Im just imagining things or if its the real deal. Im 34 weeks today and my drs office is closed so I figured I would ask on here while I wait them out.
