Hi I had my vbac 6 days ago... so fresh in my memory. I was nervous too. I have to admit, I don't think I had mentally prepared as well as I could (I had a lot of complications during the pregnancy taking up my thoughts- so I would take him any way I could get him).
I have to admit, my vbac was probably considered on the traumatic side of things compared to usual births, I tore badly (3rd degree) as bub was not well positioned and my placenta did not come out so I was sent to theatre for removal and had massive blood loss. I have to admit despite all these things I wouldn't change a thing and don't regret it for a second (I had complications post-caesar too). The sense of achievement was amazing and I still think despite my bad luck, I have recovered faster and it is still easier to care for my daughter. I am sore below from my tear, but at least my daughter can't jump on it. As soon as my toddler came to visit the first thing she wanted to do was climb on me at the hospital. Luckily, it is pretty hard for her to hurt me there!!
This post isn't meant to put you off, but just letting you know that for me personally, I still preferred my vbac delivery with complications over the caesarean. At least with the vbac I had a chance to have little to no wound, where as caesar was guaranteed 100% wound. I was driving 4 days later after my vbac and it is much easier to get out of bed. I had two other friends with very easy straightforward deliveries that weekend and they were doing amazing. Something I aimed for and didn't quite achieve, but I am still happy enough with my choice, even though I was unlucky. The docs have said i only have a 5% chance of a tear like that again so it will be a vbac (with my fingers crossed) for the next time.
I, like you was nervous, mainly about trying and still needing a c-sec and being worse off, but a friend had told me that she tried for a vbac and unfortunately failed when baby didn't engage, but she was still really glad that she tried and had no regrets. I figured, if it was something I wanted, than I was willing to take that risk. I am really glad I did and will be trying a vbac again if I decide to have more. It was very natural and empowering, scary and life changing. I was on a real high afterwards!
