*Hugs* Toni. I got some of those flashbacks when contemplating my second birth, because I was going to try for VB and of course the worst case scenario would be that it all happened over again!
From what I've heard, and contemplated far down the road, a 2nd c/s is not all that bad because you are well prepared. It's mostly just the initial emotional shock when everything goes out of control, that gets you so down.
A bit scary about your pelvis but I'm glad you've found out now (ie before the next pregnancy). And hope things come right for you, it was a huge experience for you and very frightening but reliving the scary bits only must be even worse.
