35 weeks, what to expect?

I've been having extreme pelvic pain especially when I tried to move (going to the toilet etc) Sleeping is also quite difficult for me, no matter what positions... still very pain. All those pillow techniques I've tried still doesn't work. Fluids and discharge is getting thicker and more. I have to go to the hospital once I am 37 weeks to get induce. Nevertheless, what are the sign of labor is nearing, naturally?
