Trust your OB @BabyOB. I have a really short torso so room "feels" like an issue for me - probably not though in all honesty... do you sit a lot? That might make it worse??
I know that the thought of having a c section can be scary, but if it is planned, they can be a wonderful experience too. I have had 2 - about to have a 3rd. My first freaked me out because it was an emergency. 2nd time was calm and much better. The nurses got pics of the baby coming out (just a head, then body etc) and it was - still is amazing to look back on!
I hope baby moves and you get a chance to experience a natural birth if that is what you really want. If not, just know the OB has yours and your babys best interests at heart and that next time (if you have more) could be very different feel free to pm if you want to know more about my c sec experiences/recovery etc x
