I would definitely consult with different doctors and specifically speak to some midwives. Doctors who are not supportive are known to use scare tactics, such as that, to get you to do what they want.
In most circumstances, a VBAC is safer and better for mom and baby then a repeat csection. That's a fact. If there are some other factors from your previous sections that impact that, I'd want to hear it from a VBAC supportive provider.
This is your body. If it means a lot to you, do not feel like you are trapped into having another csection. If you need one ultimately, then so be it, but if you could have a chance to do something that means a lot to you, you've got to go for it.
