VBAC clinic

hi just wondering if anyone can think or any questions i need to ask at my vbac clinic on thursday, i had a section last time as my son dropped his heart rate to less than 40, and i was only 2 cm dilated. i was labouring a while before that and all happened very quickly with a little panic from the staff. keen for another section, just a little nervous they might try to bully me into natural delivery. i'm going on my own as hubby has to work and needs to save work time for our 20 week scan, although i wont find out when that is til my vbac appointment. x
