Bh or real deal?

ok so this is my 4th I generally know the difference between the two, but now I'm curious. So thought I'd just ask what y'all thought. I've been having what I believe to be BH contractions on an off ALOT over the last 2 weeks. (I'm 34weeks btw) They're not consistent their not painful but they don't go away when I move or change positions, they're uncomfortable to say the least and they push a lot on me, this is a new one for me. I dont think ive ever felt a contraction literally pushing down on me like this, the pressure is so weird, like I'm just waiting for my water to break it feels like he's right there waiting to come out. Like I was pretty sure it was just BH but maybe they're real contractions just not in labor contractions. ? idk like I said they don't hurt which makes me think BH but they take my breathe away too. ya idk. I've had a very stressful pregnancy I have GD as well. So Has any one else felt a ton of pressure like that during a contraction?
