I am in the same boat, 27 weeks (due May 7) along and hoping for a VBAC. My doctor is supportive, but last appointment he made me worry a little. We had a follow up ultrasound because at 20 weeks the baby was not cooperating. The ultrasound showed that my baby was in the 95% for its gestational age...so they are worried about me having a large baby. Everything I have read suggest that large babies are not reasons to rule out VBAC. My biggest comfort is that the hospital I plan to deliver at has a low over all C-Section rate, and last time around the nurses were super helpful and supportive of my birth plan. I hope you get the responses you are looking for, and more importantly have the birth you desire. Best of Luck!
