My labour was loooong - regular contractions 6 mins apart starting at 2am on Saturday morning and bub born at 8am Monday morning! But I can honestly say that labour was not painful - uncomfortable and exhausting but not painful. My bub was also posterior, and even so, it never even crossed my mind to ask for drugs. I just took each contraction as it came, knowing I was one step closer to birthing my baby.
As for the birthing part, I had a vacuum assisted delivery so it was very quick and over in no time. Luckily, I only had a first degree tear.
We did a Hypnobirthing course which was fantastic - it educated and prepared us for a natural birth and the skills we learned got us through labour and birth. Highly recommend.
