Braxton Hicks or.something else?

Carrie
Its only happened a few times but it freaks me out. When I wake up my.lower abdomen is.super hard and it hurts really bad, then I try to move and it hurts even more. But usually when i manage to roll over it goes away after a few moments. Is my son just balling up at the bottom of my uterus or is that what braxton hicks contractions feel like?
