labor? or what TMI

Brianna
I'm 39 weeks and I'm pretty sure they're contractions, the pain hurts but not enough to make me go to the hospital. But my stomach hurts so bad like I have to poop and I have such a strong urge to push so I'm currently on the toilet trying to poop and nothing is happening just small trickles of pee.. Idk if I should call my doctor & my lower back aches so bad
