C section or not to c section?

Sina
I am currently 29weeks pregnant with my second baby. My first baby is turning 12 years old in May. I had an emergency C-section operation when I delivered her. My obgyn has given me the option to choose my delivery method with my second baby. Considering that my first C-section with my first baby was 12 years ago, I am able to chose between having a natural birth or schedule a c-section this upcoming July. I did a little research and spoke to a few people  (including my OBGYN) and still can't seem to chose what the best delivery method would be. Does anyone have some personal experience and can share some suggestions!??
