Another thing u may be able to try is if u are any dilated to see if they will break your water. They shouldn't use pitocin on you with a VBAC, but breaking the water might work. Also, sometimes epidurals help dilation by allowing you to relax and rest. I went 24-hrs WITH pitocin and WITHOUT pain meds before my c-sec. No one told me that for some women, they can actually HELP! So, I had an epidural this time, and I dilated. Look at it like this. You'll get one anyway if u wind up with a c-sec.
All the best, mama! You're so on my mind!!! My fingers are crossed for u!!!
