Just to add, I couldn't face sex for 10 months - combination of things including hormones and complete lack of sex drive. We had sex twice and it hasn't happened since. It's tough but we are still going - it will take time for you to process what's happened with professional help.
I knew I couldn't handle a vaginal birth because of my phobia, but now after my ecs and certain things that happened I'm not sure I could handle another c section or rather another spinal or epidural again. I've been convinced this means I can't have any more children but a year on I'm starting to think I could possibly manage it. 12 weeks is still so early and you really do need some professional help to work through this, I'm sure (just realising now I need some too).
When you are up to it, your case needs to be reported and investigated. Under NICE guidelines you had every right to a maternal request c section, and refusing that with your tokophobia is unacceptable, let alone what actually happened and the things that were said to you. Completely unacceptable.
More children is not something to worry about right now - if you decide you do want more, you can go in armed with information on your rights, the complaint you will have made by then and the notes on your first birth and absolutely get the c section you want, if that's what you want. If consultants refuse, you go to the department heads and you insist. It's completely possible and your right to choose. Please don't worry about that at this stage though, you need to focus on recovering from this trauma. Lots of hugs to you x
