I think not going vbac for me is more why you had the c in the first place. I had an emergency c sect with my son but only cause he turned posterior at the last moment and wouldn't get unstuck. I wasn't bleeding and neither of us were in trouble.
This time around I am going for a vbac as I think it is better for my body.
From personal experience too many operations on your tummy aren't good. I ruptured my appendix a few years before I had ds and then I had an emergency c-sect.
I have suffered with pain when my bladder and intestines get full from scar tissue that is binding my insides together. My dr has told me this pregnancy should stretch it out otherwise I was looking at having to pay for surgery to get it all sliced apart as because it isn't emergency surgery it isn't public funded.
I personally feel that I want to try as not that I feel like a failure or that it has traumatised me I do feel like I have missed out by not having a natural birth.
However, this is me. I pass no judgement on others who choose to have elective c-sects. It is your body and your choice. You need to do what is right for you.
But your body is more than capable (as long as there are no underlying medical conditions) to have vbacs. If you are worried about that don't be.
Good luck with your decision.
