should I go to hospital?

Okay so I've been cramping since last night/this morning and they were first in my lower tummy, then back, then tummy and back again. They're constant it seems like but they're not really going away or "releasing". I think they've eased up maybe a little but they're so uncomfortable I've had to use a heating pad on my back and it kind of feels uncomfortable to walk or even just standing. Should I go to the hospital? I just don't want it to be a wasted trip. It feels like they're in my thighs too? I'm not sure. It just feels like I'm about to start/on my period. I felt nauseous earlier as well.
