I didnt realise it at the time, but now that I have read this, there was definately a bit of time (not sure how long) a bit before I started pushing where I started to freak out and tell everyone I couldnt do it anymore and asking how much longer and when would it stop! I definately felt pressure in my butt at this time. I think during this time I started asking for more pain relief than the gas. They checked my dilation and I was 10cm.. so I suppose that was transition for me?
