VBAC feedback needed now

I had a c section last year in late March, I conceived my baby in November around Thanksgiving now I'm 30 weeks along. My first question to my OB was if a VBAC was possible and he said quick as a flash sure. He said as long as I didn't have a vertical incision on my uterus I was good to go which I don'tso I was feeling good until my mom started scaring the shit outta me she works at a rehab facility so she's around doctors and nurses all the time who've told her it's best that I have a repeat c section something my own doctor hasn't said. I know it's more money with c sections I won't be fooled but that 1% chance of rupture has always been on my mind. I would like to hear VBAC stories whether it be yours or someone close to you. Also will they check to make sure the uterus hasn't ruptured or what is the method they use to figure that out?
