Any advice to prepare for labour

I have a c section date for November 21 but I would like to try and go in to labour before this date and give birth. I can have a vbac if I'm not over my due date which is November 23. My last pregnancy was 2 weeks over and was an emergency c section. I ate pineapple and that helped me start labour within a few hours! However I am now allergic to pineapple so when the last few days before my c section date approaches what are some things I can do to hopefully kick start labour. I feel like she's going to be here early compared to my first I have so much pressure and she's already head down so I think I can"encourage" labour so I can have a vbac.
