I'm not sure you'll want to hear mine, but here goes anyway...
DS was the correct way around to start with, but flipped back to back during labour. I didn't progress after 4cm so after hours of labour, diamorphine, an epidural, and loads of G&A, I ended up with an emergency section. They had a monitor attached to his scalp and took some blood from his head--they weren't very happy with the results, and his head was being sort of squeezed the wrong way too.
Honestly it wasn't that bad. I recovered really well, still got skin to skin in the recovery room, and managed breastfeeding pretty easily (still going at 14mo).
I would say definitely rethink your birth plan, particularly if this is your first. It is a pain unlike any other (which is not to say it is necessarily worse), and I don't think you can really know how you are going to react. Things can happen that disrupt the most carefully laid plans. I think what is important is that you have informed yourself as much as possible about what is available and how it is administered so you at least have some idea of what's going on when/if it happens to you!
Best of luck, hope it goes well for you. There may still be time for the baby to turn as well!
