Time to stop listening to your ob and focus on centering yourself if you want that VBAC.
Address YOUR fears - don't let him plant more. So what, you birth on the side of the road? Happens every day, in much more remote places I'm not being glib, just (FAK-ing) a bit of perspective. Bring it back to you, your body, your baby and go from there.
PS what do you need an internal for at 38 weeks? Totally unnecessary and unhelpful no matter what the results.
