I’m curious if anyone having a second planned c section had unplanned VBAC?

I’m curious if anyone having a second planned c section had unplanned VBAC? With my first I had an emergency c section. This time around I have a scheduled c section but keep feeling in my gut that I will somehow deliver naturally. Anyone gone through this? Did you know somehow that you were going to have your baby vaginally the second or 3rd time?
