Good luck. I am at Kings in London and recently had my discussion (midwives and consultants all agreed before but never formally set it in stone before 35 weeks) the other week for ELCS.
Had an ELCS abroad for my first (breech) Ob Gyn recommended not going for VBAC as my surgery for Asherman's (interuterine adhesions caused by rough D&C) meant the rupture risk was higher.
I was nervous I'd be pushed towards VBAC but apart from one consultant, who rather poo-poohed my Asian ob/gyn's reasons for a repeat section "Oh, they all say that in Singapore...." it was all consensual, adult and I felt listened to.
I would recommend reading and printing and taking with you the NICE guidelines and what the RCOG says about VBAC.
My reasons were:
Rupture risk. Small, but when it goes wrong, it is grave
I cannot be induced with prostaglandins and given I am being watched for blood pressure and may have to be induced, I'd rather not be induced manually.
The Asherman's having thinned my endometrium. I don't have my notes but it's an uncertainty I can live without
I would need close monitoring and protocols are set for the various phases. This makes doing things 'my way' and increasing my chances of a straightforward and active labour much lower.
I don't think facing a 30 percent chance of an EMCS after possibly labouring for a long time are good odds. I wouldn't bet on them. Since I don't have an emotional investment in vaginal birth I don't feel these odds are worth it for me.
Safe for baby, risk load is on me, which is fine by me.
If I could guarantee one on one midwife care and giving birth at a good time in a fully staffed hospital, I may have considered vbac. But that's not the reality of my hospital
My baby was safe, my recovery was fantastic with my first and so I am happy to repeat this. It meant enforced bedrest for a couple of days which helped breastfeeding as I just had her on my breast almost constantly (and ahem, still feeding her 2.75 year's later)
(Plus I don't see the point of knackering myself in two areas, but I would ever say this!)
What puts me off is 2 nights in a post-natal ward!
Good luck.
