Labor pains, and self induction? can someone help?

my upper back, side, and legs are hurting when i move and im 39.5 weeks pregnant iv had no sings of labor or thats how i feel and my contractions dont even hurt.. i cant get in touch with my midwife to ask her about it and the hospital wont tell me anything. does anyone have a clue of what is going on?? And if its not labor pains can someone tell me how to speed it up and to "self induce" and ya i know he will come when he wants but i just want to "try" to speed it up.. and has anyone been induced by eggplant parmesan?? And does nipple stimulation actually work and if so how do you do it??
