I really wouldnt worry about it being breech at your 20 wk scan. Although i can understand your anxiousness as you really want a VBAC.
I am 23 wks and my baby is laying across my belly still. I said this to my OB and she said it has plenty of time to turn yet and not to worry.
In reference to you thinking that the hospital has classed you as high risk unecessarily because of you wanting a VBAC, i think they would be negligent if they didnt. You will need constant monitoring throughout your entire labour to make sure that you dont suffer uterine rupture, im sure you know the risks associated with a VBAC but i thought i would just try to explain why they have labelled you "high risk".
