hi there
im short, about 5"2, i have size 7.5 feet - not overly small, in fact fairly large for my overall size... anyways after much pushing and hours and hours of labour i had to have a caeser to get my girl out, who was 8lb7... the obstetrician who performed the caesar said he thought i would only have a 5-10% chance of having a baby vaginally due to my pelvis... now i am not sure how he could tell this, and how valid it is etc etc etc, all i know is i tried dam hard to get that baby out and couldn't, and she had indentations across her head from my pelvis (still does). I am happy to have a caesar again next time as my labour was the worst thing in the whole world and if i had to go vaginally, i honestly can't say if i would have another. of course everyone's experiences are different, i am just unfortunate to have had a horrid one.

best of luck - by hook or by crook your baby will come out one way or the other and once she (or he) has arrived, the way in which she came into the world will be so irelevant.
