BH or real contractions?

Kim
I'm a FTM, 38 weeks and 3 days into my pregnancy. I've had what feels like bh contractions for the past 4 hours on and off but currently been getting them every 7-8 minutes or so.. When I get them, my belly gets rock hard and baby stops moving. Soon after it's over he'll start moving and kicking again. I also feel tiny bubbles at the bottom of my belly? Not sure if anybody else ever experience the same problem as me. I just need to know if they're real contractions or not. I have no real pain when I get them. Just feel real uncomfortable and unable to move.
