If it helps, when I first spoke to my consultant I asked (and they answered)
- if it's moved, can I have a vaginal birth? ( yes, but it's not a cut off to low risk at 2cm away. There's still a good chance of a significant haemorrhage and emcs.)
- what are the risks of giving birth when it's 'just far enough' away ( basically as above, it's an arbitrary distance, there's no sudden drop to a lower risk and there is a degree of error in measurement. You still have a chance the baby will trigger a bleed as they descend. If that happens it's crash section time.)
In the end, and after a very thorough examination, they found foetal vessels near the os, so for me, a definite no no for a VB.
I also asked her (she was the head honcho for the entire region) that taking emotion out of it, with her experience seeing everything that goes right and wrong, what would she do? She answered 'section, without hesitation.' So I'm with your dh. Mine had a very similar reaction actually - he had been worried that it'd be marginal and I'd go for a vb and it'd go wrong...
38 weeks is the sweet spot that strikes a good balance - late enough that the baby is sufficiently developed and technically full term and early enough to be reasonably sure that they catch you before labour starts.
I know it's disappointing but try to take emotion out of it and look at the risk/benefit ratio. It's one day in your life, the important bit is how you raise your child, not how you get him out into the world. I suppose it's like people saying that unless you have a big 'perfect' white frothy wedding, your marriage is doomed - it isn't, the wedding is just one day, the marriage is the hard bit, and the bit that's more fulfilling.
Good luck with whatever you decide, but my opinion is with your dh and your consultant :)
