I've just had a quick look at your pics and you're NOT BIG - well IMO anyway - I'd say that you're pretty average size - well the point I'm trying to make is that if you want a VB I'd stick to my guns about it - if they can't give you a definite reason besides 'maybe you'll need a C-sect" - i'd insist on wanting to atleast try for a VB - we're all at risk of having C-sect but from the looks of you I wouldn't say that your size would be that much of an issue - btw I'm also pleasantly plump (size 16ish - depends on how much lycra lol) and I went onto have a VB and my size was never mentioned - not once - i wasn't even weighed - all accept for one time when this idiot doctor who i had never seen before insisted on it - but then again he was an idiot and asked DH to leave the room whilst he took my blood pressure - so do i really need to say anymore.

Stick to your guns and be confident in what you want - go prepared and ask a million questions as to why they are doing certain things etc - but most of all have faith in your self - you can do this and there is no reason why not

Goodluck
