Braxton hicks contractions?

Katherine • Pregnant with first baby with my hubby!!
I keep getting this tightening feeling in my stomach. Every couple of hours and then a heavy feeling in my uterus 
I'm 32 weeks almost 33 
I just don't know if they're real labor contractions or Braxton hicks I would imagine I'm not going into delivery already, so I'm guessing they're just practice contractions, but just wanting to confirm that they are that.
