Kicking/Popping Sensation When I Pee??

I go to sit to pee and barely anything comes but I feel these kicking/Popping sensations and I pee a lot. I know this can't be my water because I've felt it three times now. I don't know what it is. Can somebody please tell me, if they've had the same issue. I had bloody show earlier and contractions haven't let up at all, but we are waiting for my water to break before going to the hospital. No there hasn't been any fluid come out when I stand afterwards so I'm really confused. FTM lots of questions today I guess.
