Pelvic Pain

So, I am 32 weeks pregnant, and I have had pelvic pressure for a couple months now, but as of three nights ago, it has went from pressure to pain. It started when a few nights ago I woke up to pee and my pants were soaked - at the time I figured it was sweat. But when I woke up in the morning I could barely move due to the pelvic pain. It has now persisted for three days now and I am starting to wonder if the wetness was my water and I am starting early labour. I haven't been having contractions though - at least to my knowledge (this is my first pregnancy). Does anyone know what may be going on?
