VBAC/TOLAC

Have any of you ladies had a vbac? I had one previous c-section. My daughter was facing up so I couldn’t deliver vaginally. She’ll be 3 soon. My blood pressure is good so far. Has anyone had a successful vbac? I’m scared and nervous and excited because I found a doctor to do it. I’m just worried. Any tips? Anything I should do to prepare myself? Baby is due sept 2nd. Share your stories please! Did you end up needing an emergency c-section? Was everything okay? Risks? Pros? Thank you!
