I chose to have a CS, so I'm no help to you on the natural birth thing, but I wanted to reassure you that if you DO end up having a CS, they are not bad at all. Mine was honestly a fantastic experience.
I am fully supportive of women being able to choose the sort of birth they want (barring emergencies). Good luck with whichever way you end up going. (I would put a smiley in here but for some reason it's not giving me the option in this new format!)
