However, it sounds that any potential pregnancy is a relatively long way off in the future, although there is no harm in thinking some things at the moment.
It does sound as if it'd worth speaking with your/a (sympathetic) GP- going for some sort of pre-natal counselling might be worthwhile
As it goes, the NHS will most definitely carry out an elective CS for maternal request, you may have to jump through some hoops first, but it is possible.
My DC1 was born via elective CS for maternal request- saw the consultant, she booked me in for a date, then had to see another consultant as it was hospital protocol.
I also had to see a consultant psychiatrist to check I was of sound mind to make this decision- it lasted all of 10 minutes and he gave me the seal of approval for a CS
If the initial consultant refuses, you then must be referred to another consultant who will agree to the procedure. If the entire hospital or Trust is 'no go zone' for maternal request CS, then you will need to find another hospital who is agreeable.
Last resort is to go private, but with the NICE guidelines you can usually get agreement to an elective CS, but it may take some time.
I was very lucky that my local London teaching hospital made my first CS a very straightforward process to organise.
The birth and my subsequent recovery were complication free, DC1 was in perfect health. DC2 was born last year via CS, again no complications and v healthy- recovery was better than first time round.
By comparison to one of my good friends who had a "natural" birth- she had a protracted and uncomfortable recovery, birth centre initially followed by failed ventouse, forceps with episiotomy and a severe 3rd degree tear (had a couple of postpartum surgeries for this)
But you could say that I was simply lucky and she was unlucky.
What I do know, is that all I've written is a reflection of the fact that an elective CS was absolutely the right mode of delivery for me.
When the time comes, you will need to think more seriously about what is the right way for you, try not to get too stressed out about it at the moment. Also, when you are eventually pregnant, you want to be able to enjoy this amazing process
Good luck!
