How can I induce my labor at home?

I am almost 39 weeks pregnant and set to be induced next Monday, Instead of being induced in the hospital I would really like to jump start my contractions here at home and have her come without all of the medicines. I have tired sex, eating pineapple,turkey,unripened papaya, I've used Primrose oil, had sex, and walked and walked and walked... nothing seems to kick in into full gear. I am 2-3 cm dilated, and about 80% effaced. I have been having horrible contractions the last few days but nothing that is close enough to go to the hospital. Does anyone have any other ideas?
