How do I get myself to efface/dilate

For starters, I'm NOT in a rush to get baby out due to impatience. I'm approved for a vbac but I can't go overdue, and I have to be at least somewhat dilated in order to be medically induced. At my appointment today, I was not dilated and effaced and baby is still way up in there. I have 2 more weeks or else I'll need a scheduled c section. It's my 4th baby and my 3rd was a c section and my recovery was horrendous.

With my previous pregnancy, I tried raspberry leaf tea (gross), lots of pineapple, sex, nipple stimulation, lots of walking....nothing worked. Any tips?
