Scheduled c section changed to vbac

la

Just wondering if anybody had a scheduled c section and ended up having the baby vbac because he/she came too fast? I know doctors plan c sections about a week in advance but I'm worried what would happen if baby came fast. I hear stories sometimes of 15 minute labor/delivery 😳

How did it turn out? Any negative issues that arise from doing unexpected vbac? I had c section 7 years ago so pretty sure I'm healed up all the way.
