I'm a little late to share but, long story short; I had a beautiful baby girl March 20th via natural VBAC!! It was the most fantasic experience. It was a long and frustrating road but, SO worth it.
We had a lot of obstacles: cervical laceration, breech at 36 weeks then transverse then breech again! I was not allowed an epidural because, I was delivering at a hospital that does not "approve" of VBAC, big scary consent form.... BUT....It was a picture perfect natural delivery and worth all of it.
There were so many times I thought i'd just go with the c-section. I was just as scared to go natural as the VBAC it self. But, what i found REALLY helpful was at 39 weeks I advocated for an ultrasound to measure the thickness of my uterine scar. This does NOT garuntee I will not rupture but, it gave me some peace of mind to know going in, I was not thinning already.
I hope this helps.
