My 1st was undiag breech & 2nd was posterior which was confirmed after obgyn broke my waters when still only 5cm dialated (to speed things up), then obgyn could tell that bub was facing up. Bub didn't turn though so ended in c/s even though was fully dialated & fully effaced, head was just too far up due to facing wrong way.

I found back pain & tummy pain during contractions & felt the best posi was kneeling on floor cushions & leaning head/arms over bed & DH &/or doula massaging back & tummy. In the end I was begging for the epi though but was too close so couldn't have one, until in theatre for c/s.
