Sensation of a constant contraction

Katy

I keep feeling like my whole abdomen is so tight and when I touch it, it’s hard as a rock. It’s been doing it since last night. I’ve drank plenty of water, I’ve sat down, nothing is helping. I’m not in pain at all, but it’s a little uncomfortable and very unnerving. Could this just be baby’s position or am I really having a never ending (it seems) contraction.
