tips to progress labor?

for medical reasons (high blood pressure and mild cholestasis) I have to be induced next week at 38 weeks. I am trying for a Vbac so my options are limited w/induction & I may end up needing a c section. that being said, I was checked Friday and was dilated 1 cm/0% effaced. today I am almost at 3 cm/ and 80% effaced! (fairly consistent contractions too but not that painful)  my doctor stripped my membranes to help start labor & we are hoping I can go naturally without having the induction. any tips to get labor going? so far I've been using sex & eating dates & walking a lot.
