I wasn't aware that my DS was back to back at the time - he had started off in the right position - but discussions with midwives have since confirmed that he likely ended up back to back...and my Mum and I concur that he was definitely facing upwards when he came out!
Apparently it was a typical back to back labour - waters broke dramatically and contractions started and continued in a half hearted fashion over a period of a couple of days until we reached the point that an induction was recommended because of the risk of infection.
The contractions felt very strange compared to how people usually describe them (i.e. no period type pain early on, no lower back pain later on) and I could not sit down comfortably so either had to be walking, on all fours, or lying on my side.
When we went back into hospital for the induction I had managed to dilate a couple of centimetres so they didn't bother with the pessary but put me straight onto the syntonicin (sp) drip at 5 p.m.
After a couple of hours I was feeling quite uncomfortable so the midwife offered me some gas and air. I enjoyed the G&A quite a lot and the next 5 hours were quite good fun and the pain manageable provided no-one talked to me during a contraction!
When I was about 8.5cm dilated I had the overwhelming urge to push (possibly because they had to up the syntonicin dose quite a lot to maintain regular contractions and possibly due to DS's position as well). It was pretty difficult not to push and I found this quite distressing.
When I finally became fully dilated I was very tired and kept falling asleep between contractions. In hindsight I wish I had just gone with the induction option earlier in the day and I might have had a bit more energy.
After 1.5 hours of pushing (and starting to wish someone would suggest a c-section) the senior midwife appeared and they put my legs in stirrups, told me to put the G&A down (I wasn't focussing enough) and sternly told me to push each time I had a contraction. This was just what I needed tbh and I managed to push DS a fair way down, the obstetrician then appeared to perform an episiotomy and ventouse and DS was born very quickly after that (8 hours after the drip had been started)! The sensation of the ventouse and the stitching afterwards were the most unpleasant parts and I did have some nightmares about it afterwards but I don't really remember the pain of it now (and DS2 is due in 4 weeks).
My motivation to not have an epidural was my fear of big needles!
