Anyone have a successful VBAC?

I’m 30 weeks and 4 days pregnant with my daughter and I have about 9 weeks left. I’m due in June. I will be having a VBAC and I’m nervous on how this delivery will go. With my son, I had a emergency c section because he was too big. He was 9 lbs 14 oz. I’m afraid my daughter may too big for me to push. But at the same time she’s measuring smaller than my son this time round. I was wondering if anyone else had a successful VBAC after having a c section due to having a big baby?
