32 week back pain

Okay, I'm 32+1 and for a few days now have been experiencing low back pain into my pelvis area any time I sit down, lay down on my back or my side and contractions every so often. The back pain is constant but pelvic pain is sitting or laying. I've also noticed I've been very "wet" when I go to the bathroom for the past week and a half. Could this indicate early labor might be coming? I'm a first time mom so I'm not sure exactly what is normal. I had a miscarriage earlier this year at 8 weeks so I've never gotten this far.
