I had a successful VBAC with my second after a similar situation to yours. I pushed for 34 hrs, no drugs, wanted a natural birth, then 2 hrs with an epidural, but I was stuck at 9cm and my baby's heart rate was not tolerating the contractions so I ended up having a c-section. For my second my midwife never considered for a second that I would need a c-section given that there was no physical reason why I couldn't have pushed him out, save I didn't continue to dilate. It doesn't sound like your situation was physical on your part either except that your son's head was turned funny. I dreaded a long labor the second time around given my first experience, however, it went SO much faster. Contractions started around 3:30 am, and we got to the hospital around 8 or 9 am, and I was already almost fully dilated and my water broke as I was trying to get into my hospital gown! I pushed for 1.5 hrs and out my son popped! My first was 8 lbs and my second 7 lbs. It was SO rewarding and I was so thankful to have had both experiences. I say try for the VBAC.
I have a friend who was also going to try for a VBAC with her second and ended up scheduling a c-section based on the estimated weight of her baby and her doctor not wanting her to try and push out a large baby. They were totally off on the estimate and her baby was smaller than they said. She never got the chance to push.
Look, you've already had one c-section. You know what to expect and what's involved. If you try for a VBAC and then they decide you need the c-section, it's not emergency, emergency. You are considered higher risk to begin with given your history, so there will be plenty of people on hand to monitor you. Give yourself the chance to push. Then if you do end up with the c-section, you will know that you at least gave it a try and it really was the best thing. They will be ready for a possible c-section and you will end up, either way, with a little baby!!
I suggest getting the opinion of a midwife. They are WAY more likely than an OB to let women try for VBACs. OB's tend to push for the c-section because of the slightly higher risk associated with a VBAC. Get the stats from a midwife, it's still less than a 1% chance something could go wrong. Also, I adore my midwife, but she was away when I went into labor and I had to go with the other midwife in the practice. I was concerned because I'd only met with her once before and wasn't sure we clicked. It ended up to be totally, totally, fine and we totally bonded over the experience (how could you not!).
OK...this is a lot. Please let us know how it all turns out!
