Need advice

Help! I'm 37 weeks and 3 days, my back won't stop hurting at all! I've took a bubble bath and all, could this be back labor? It hurts so bad I'm almost in tears and I can't sleep. Should I go to the hospital or lay here and wait it out? My baby won't stop moving at all, he's being extremely active at 1:30am. I need advice!
