Unbelievably desperate!

I am 39 and 2 today, I have tried primrose oil tablets, having sex, eating spicy food, getting stretched or membrane sweep as most of you know by my doctor twice already, and last not but least drank castor oil, so far all any of it has done is dilate me 2-3cm and make my mucus plug fall out. I have not felt a single contraction, the only back pain I feel is in my upper side, ribs, and I felt my pelvic bone and hips stretching a few times. Is there ANYTHING else anyone can recommend me to induce my labor already before I go over my due date?!
