I had an emergency section the first time, and elective the second.
The first time around I was two weeks overdue, then a couple of sweeps got me into grudging labour for 30 hours, vomiting the whole time, after which I was still only four cms dilated. Heart rate went bonkers so was rushed into theatre.
Second time I wanted to have a home vbac. Had a birth pool in the kitchen and everything. I went 14 days overdue again and when I was examined the day before I was due to be induced (they'd wanted to do it sooner, I wanted to wait, we compromised on two weeks) my cervix was so high and tight the MW couldn't even get a finger in to do a sweep. At this point, things were sounding very familiar. Because they were leery of letting me wait any longer, I had the choice of being induced with a balloon and forced open, which from all the evidence had a high risk of going the same way as last time, or walking into theatre.
The point is that I did want to try for a vbac but not at all costs. My main priority was that I had a more positive experience than the first, which was horrendous and scary (as I'm sure yours was) and, I believe, contributed towards my firstborn being rotten at breastfeeding. I had my ideal plan, but changed it at the last minute to ensure a good experience. I believe it was the right decision; my elective was loads easier to recover from (this is because they're far gentler with your innards when they're not in a hurry) and the birth itself was lovely: candles, music, immediate skin-to-skin and laughter, none of which I'd had before.
You can change your mind at any point. If a vbac is important to you, have that as plan A and see how you go. If you get OC again (at what point are you likely to know?) then you can shout for a surgeon.
Best of luck!
