Braxton Hicks waking me up

So I’m 36 weeks and my braxton hicks have been happening a lot more frequently but last night/this morning they keep waking me up with deep lower back pain and the urge to poop. It’s starting to hurt. I realized how frequent they were so I timed them. They’re coming in waves of 10 minutes apart and lasting 45 seconds to a minute each time. Super powerful. Could this be early labor?
