Vbac possible?

Britt
With my first I was induced and never experienced going into labor naturally then ended up with a c section because he literally could not fit out of me. He was a week late and weighed 7 pounds 11 ounces. I'm now pregnant with my second and hoping for a natural vbac but at my scans he was already 6.5 at 34 weeks. I have a feeling he will end up being too big for a vaginal birth as well. Has anyone else experienced this? I've been having some pretty strong contractions and I've dropped. It almost feels like he's trying to get into position but my contractions are unproductive. I'm 36 weeks and I really think they will want to schedule a c section.
