Suggestions on how to dilate


I'm 39+4 and not dilated at all. I heard that induction isn't as successful if your not dilated at all. The dr has started scheduling me for induction at the end of next week. I'm wondering if there is anything I can do to help dilate. Baby is engaged and in proper position. It just seems my body isn't cooperating. I've heard walking, sex, eating pineapples etc helps but wasn't sure if that helps dilate you or just helps start contractions.
