Am I overreacting?

I'll be 31w tomorrow and am having lower uterine cramps and just don't "feel right." Granted, I did a Zumba class earlier b/c I'm trying to exercise more to help with anxiety (doctor approved), but I'm not sure if the cramps should be concerning. It doesn't feel like contractions and isn't timeable or anything. Baby is still moving but not as much as normal (could just be sleeping).  It's been this way for a few hours. I feel dumb calling my ob (I was just there for my checkup earlier today). Thoughts?
