Pelvis fracture and delivery

Last year I was in a bad car accident and fractured my hip, pelvis, and sacrum. No surgery was needed but still have pain. Not real bad just a constant feeling in my hip, sometimes in my pelvis and getting more intense as my pregnancy progesses. I've had 3 vaginal deliveries and would like this one to be as well. My dr. recommended a c section to be safe. She said it could be fine vaginally and it could not be. They were hairline fractures and I don't want to cause any permanent damage or be unable to walk after I have the baby but I really want to do it vaginally. I like to go home the next day, and not know when the baby will be born etc. Plus this is my first baby with my fiance. It's all been very unexpected but a welcome suprise since my tubes are tied. This will be my last baby and want it to be the best experience possible but also the best outcome for recovery for me also.
