Hi ladies. I can really use some help and advice right now

I'm 41 weeks and my belly is tightening like crazy on / off .It's been doing it every 10 mins for the past 40 minutes...It just feels like severe pressure in the middle of my abdomen, no pain though...Like someone is taking a huge elastic band and tightening it around my abdomen and chest and then release slowly after a few minutes..I timed them and they were at
 

8:30 pm

8:40 pm

8:50 pm

9:00 pm

Is this BH or real labor contractions?

With my first pregnancy I had stabbing/slashing type pain on my sides and lower abdomen like menstrual like cramps. I never had tightening feeling like this.. I can almost feel it in my throat or something..weird :s

Please help!
