I am 36 week and I am cramping a lot I get some that r bad and some not so bad. I tried to go to the restroom number 2 (sorry tmi) and when I was going to push I felt like I was pushing the baby out. I can't go number 2. I have a doctor appointment on Wednesday so Idk if I should wait. Has anyone felt pressure down there and like they have to pee but nothing happens.
