BH or real deal? 😳

So I’m 34 weeks and 2 days (about to be 3 since it’s almost midnight), anyways I started having like these cramps that make my stomach hard it went from being hard at the top of my stomach to the bottom. Baby is still moving, but man do these cramps hurt/feel uncomfortable. Like it kinda hurt to walk at first and I’ve been drinking water, but I don’t know if these are Braxton Hicks or could possibly be the real deal. I’m a FTM so I always thought my water was suppose to break before I go into labor. I’m pretty sure it’s BH, but just not entirely sure 🤷‍♀️ just feels like strong period cramps. The hardness goes in and out, but the pain lingers.
