Braxton Hicks!?

So every morning I wake up I feel like there is a huge rock in my stomach most of the time it’s ok the right but occasionally I will have it on the left or in the middle of my stomach but regardless it hurts! I usually don’t notice it so much during the day but today I haven’t had much to do and my daughter has been playing with my sister all day so I haven’t had to chase her around like I usually would and I’ve noticed it’s happened a few times. I don’t know if it’s lack of moving around today or the fact that I’m usually never sitting down and it’s getting to me or what. I never had Braxton Hicks with my first so I don’t know if that’s what I’d happening but if so I’ve had it every morning and I’ve been woken up once or twice with it hurting one time it hurt so bad I was getting sick and had to take a warm bath and lay back down and it stopped hurting soon after that. Should I worry if it is Braxton Hicks having them so much? Does it mean I may not go over my due date or even to my due date? I don’t really understand the point of them considering it’s not like real labor at all their just irritating! I know I may sound stupid in this but I’m literally so confused as to what is going on.
