You should be able to try for a VBAC up until your csection date. You could try nipple stimulation for 20 minutes on each side, sex, walking alot with long strides, and squats . I used cumin seeds 2 TBLSP of it and 6oz of water boil it together for 5 minutes and drink when coo but you need a coffee filter to get the seeds out. It's called cumin seed tea. I did this with my 3rd baby and I got labor started in just 2 hours after drinking it. I was 0 everything to 50% effaced and fingertip dilated.
Acupuncture worked great with me, along with lots of walking.
