Braxton Hicks contractions on one side?

calm down

Did you ever have braxton hicks contractions only on one side? I'm getting pains on my left side and my left back and I think my stomach is tightening when I get them. But it doesn't hurt all over. It's more like a sharp pain that comes and goes on my left hip bone and I have to hurry and sit. I'm 39 weeks and I've never had any contractions or labor scares.
