What would you do if you were me? Vbac or Repeat Cesarean...

Taryn
Kind of long but hoping someone can help.
I had recently made up my mind to try a Vbac after having a successful vaginal birth with my first son and then a Csection with my second son due to breech position. My Dr's say the choice between Vbac vs repeat Cesarean is up to me as long as I know that the small chance of uterine rupture could be a deadly complication (no pressure right?!)         I also have uterine didelphys, or a double uterus. My concern is that I may be at an increased risk of uterine rupture with this uterine abnormalaty. And no I haven't gotten to ask my Dr if my double uterus puts me at an increased risk yet but I have tried researching it and there's basically no info out there on this rare situation. I'm starting to wonder if Vbac is safest option... 
The baby is head down and I am 36 weeks. It's been almost 9 years since my Csection; giving the scar plenty of time to heal. I know there are serious complications with a Csection as well as a Vbac. I don't know what to do! Any help or advice would be greatly appreciated. 
Here's what my weird uterus looks like compared to a normal one:
