Like how reliable is measuring scar tissue on ultrasound? Is there anything that helps in your favor to make your risk of uterine rupture or complications less? What makes a good candidate and what makes a bad candidate? Or is there no rhyme or reason and it’s all just up in the air until shi* hits the fan, or doesn’t?

My births are as follows

Child 1 : 2010 vaginal

Child 2: 2012 c section

Child 3: 2015 c section

Currently pregnant with number 4, and considering a VBA2C, but want to have all the facts considering I’ve had two sections and I would be surprised if that didn’t affect my candidacy for a vbac. Thanks!
