I had mixed feelings right to the end second time round. I'd had an emcs first time round after an 8hr 2nd stage, ventouse, attempted rotation and a lot of trauma. I don't think that you ever feel truly confident second time round after a difficult first time and I realised quite quickly it was because neither option was 100% what I wanted. I would have liked a natural delivery without the trauma and intervention but knew firsthand how wrong that can go and knew if I opted for a vbac, there was the chance of another emcs. With an elcs, I had to shut the door on any chance of vaginal delivery and I didn't want to do that either.
In the end, the only option was to make a choice and exercise control within that as far as possible. So if you choose a vbac attempt, be clear with your cons what you would like within that, discuss how and why decisions would be made, when you would move to intervention, how long they would like to let you labour. If you choose elcs then do you want the screens lowered, music, skin to skin etc. You can only make decisions on the variables available within the option which you think suits you best. Probably not perfectly, but best for YOU.
I attempted a vbac btw and after a 3 day labour.... had an emcs! BUT it was much calmer than first time round, no trauma, I wasn't exhausted and sobbing. I recovered quickly, up and around later that day, no pain relief needed and was back running at 8 weeks. I felt in control and that was the difference.
I kept telling myself that the labour and delivery were just the process by which the baby got here and all I could do was make it as positive as possible regardless of method and look forward to bringing another baby into the world.
