Cramps

I'm 34 weeks 2 days and for the last 5 hours or so I've had lower back cramps. Sometimes moving to the front but mostly just consistent in my lower back. I've drank water, moved around and even slept a few hours but I'm just not sure what to do. It's almost like a period cramp but I don't think these are contractions are they? It's nothing I can time it's just there. I still feel baby move too.
