pains and discharge.

Okay so last night I started getting these sharp stabbing like pains what feels like is right at my cervix and she was moving right behind my pubic bone so I had to spread my legs and sleep with a pillow in between my knees just to release the pressure, today I've been having the same pains again but they're absolutely breath taking and I double over in pain, I tried to "check myself" but didn't try too too hard because I can barely reach but I'm having those god awful pains again with increase of white thick discharge and lower butt/back pains. 
I keep feeling the urge to push but I mean I'm not in labor and my water still seems to be perfectly intact. I'm just confused because I don't remember getting this with my first. 
Any idea what this could be? I'm 35w+2d due November 7th.
