VBAC questions

Sa

I'm pregnant with my second and due in May 2020. My first was a c section December of 2016. What types of questions should I ask my doctor and things I need to be 'armed with' when weighing my options between a VBAC and another c section?

My brain won't turn off about the worry of a VBAC and the pain of another surgery. Help a girl out. Haha
