Like you, I had my DS's bum firmly wedged in my pelvis (surprised it didn't make a cork popping noise when he came out). They only discovered he was breech at 37 weeks, had failed ECV at 38, then spent the next 10 days in floods of tears because I didn't want to have a section.
There was no choice given, though they did scan on the morning of the section to see if he'd turned, and would have induced that day if he had.
In the end, I had him via ELCS at 39+2. And I know everyone says that once the baby's in your arms, you won't care how it got there, but I was still, up until about 2 minutes before he was born, spitting feathers about having to have a section. And then there he was, and it was absolutely true - didn't care, had this gorgeous creature and couldn't have been happier.
The surgery staff were all wonderful - it was like a little party for me and the babe. Having a section is very surreal, and surprisingly quick, but they were so professional and I felt incredibly well looked after.
It does bloody hurt afterwards, but not as badly as I feared. I recommend some giant pants to cover the scar. And some prunes in hospital - helps with the first poo...
If you have any questions, do ask, as I had a couple of friends talk me through theirs beforehand and it really helped. Just made it seem like less of a mystery.
Hope these last few weeks are okay for you.
