Will they not consider low-dose pitocin? They don't have to blow the baby out, but AROM with low-dose pit works very well and with very minimal risk for UR. They might could even do a foley bulb the night before for cervical ripening. I wouldn't let them rupture you if you're very high. AROM with the baby above -2 station has a definite risk for cord prolapse.
I'm sorry you are going through this. Spontaneous VBAC labor is clearly preferrable, but VBACs can be induced. And, of course, an ERCS isn't the end of the world either, but I know that's not your preference. I wish you a peaceful birth experience, knowing that in the end, either way, you will have a beautiful new baby.
I am glad they are letting you go to 42 weeks.
You do have the option of NST, fluid measurement, doppler umbilical measures, and go beyond 42 weeks---you will be close surveillance.
Foley bulb day before a ERCS--along with breast pump induction---worth a shot!!
Let us know--and remember----you are VERY likely to go into labor by 42 weeks!
