Inducing naturally

I'm 37 weeks, measuring bigger, midwife says she'll be surprised if I go over my due date, but I have been having sex(when boyfriend feels like it), pumping with my breast pump every night, bouncing on a ball, taking evening primrose, drinking green tea, raspberry leaf tea, detox tea, and regular tea, and walking! Is there anything else you've tried that has worked? Or heard anything that might work for that matter? I'll try anything! (And I don't want to hear "let baby stay in as long as possible")
