Painless contractions making it hard to breathe?!

Katie • CrossFit/Wifey/Momma2Be
After being monitored today I found out I am having contractions very irregular though. Since I have been home I have noticed them more often and regular but not painful just uncomfortable. They bunch my stomach up so hard that it's almost hard to breathe like there isn't room. Has anyone else been experiencing this? 37+4 today! Also what is the best way to track my contractions?
