Interesting I was at 6cm when went into hospital and at that point DD was assessed as being anterior, I never progressed from there despite synto and epi being given after about 5 hours of no further dilation (cervix was just get red and irritated they said), ended up in emergency c/s and DD was found to be posterior. So it could be that she turned shortly after I arrived in hospital and that is why it stalled - I was still having contractions but no dilation and I think after about an hour in hospital the contractions changed a little and didn't feel as effective and just hurt more.
