Vbac after 2 C-sections?

I've had two C-sections. An emergency with my first and I planned with my second. I'm having my third on 3 weeks and I'm not looking forward to it at all. I was wondering if I should bring up the possibility of a vbac to my doctor. I just don't enjoy having to undergo surgery and the recovery is not fun. I would much rather try for vaginal birth but I'm worried because I tried vaginal with my first and it went so badly. I ended up having an emergency C-section and it was pretty traumatic. I'm just nervous that'll happen again and I'll end up with a C-section either way. So to cut the risk I just go along with the planned C-section. I have an appointment coming up and I kind of want to ask my doctor.
