Oh, totally. I'm a basketcase. This is #3. Its not pain I'm worried about though.. I know it'll be hard and I'll get through it. I guess thats not a source of anxiety because its the one thing thats certain! #1 was blissfully unaware.. I did LOTS of reading and considered myself pretty darn well informed, especially for a first time mom. Ended in a c-section due to OP/asynclitic position :( I thought if I did everything "right" I'd be granted immunity from having a cesarean unless a true medical emergency came up :P Well, dd showed me! Being humbled is a good thing though.. So #2, successful hbac. A little nervous then because  I'd never birthed vaginally and I wanted SO MUCH to have a vbac. And my innocence was gone so I knew there was simply an element of "luck" to birth.. can't control it, just go along for the ride, have good support, hope for the best. Now with this one I'm 32 weeks and I've been in this irrational state of panic for weeks. I'm worried about... having a big baby. Punchline? ds was 10lbs 2oz!! rofl. So, apparently my pelvis can accommodate a big baby. But then there's that little voice that says "sort of..." because he had SD. It was not traumatic/scary, handled great, and aside from taking a few minutes to transition to land breathing and perk up all the way, he was just fine. No injuries. So then there's  that little voice "what if this one is like 12lbs and I have repeat SD and aren't as lucky that time" And then there's some "I got lucky last time" and paranoia that having a vbac at all is just luck.. and I can't get lucky twice and will be doomed to a RCS. Geez! You'd think having done it before I could have a little bit more confidence?!
