labor pains or no??

I'm 37 weeks and 4 days, every time i get up or pee i have HORRIBLE pressure on my pelvis, and it feels like the baby is just gonna fall out and it hurts. As well as i'm having alittle back pain, as if they were cramp pains. & my stomach tightens & stops. i don't want to go to the hospital cause i'm just afraid of them giving me a shot to stop it all and getting sent home. anyone else felt like this??
