Hello - I did and it was FAB! It was my second, so had done it before, but had an epidural, G&A, Pethadine so had no idea what it actually felt like. The first time I was petrified, drugged up and had some painful damage, but really wanted to experience it with my 2nd properly and have a natural as possible time. I read the marie mongon book and listened to the CD etc. In labour I downloaded some relaxation music instead and did the breathing and visualisation.
I was induced, and it took 2 days to get me going which was invasive and uncomfortable - that was the worst bit, but still not too bad. I was on my ball, relaxing to my music and doing the 'breathing down' bit. I could feel my body and muscles doing their thing, and then said to the MW that he was coming and was moving down. She said she doubted it as I was very calm. Too much info here, but i felt like i really needed to go for a no 2 (which is the baby moving down), and the pressure was powerful, but not painful. She was quite dismissive in a polite way and said they would have a look at my cervix when my contractions started. I was having tightenings, but they felt powerful, not painful - I did manage to breath them away, I was also on the drip which apparently makes them harder and faster. Anyway, by the time they did look i was 7cm (gone from 1cm in less than 2hrs). Within an hour he was born. I did feel a bit panicky, but only because my body was working like a machine and i felt like my mind wasn't ready for it, I was a bit like "Hang on a minute, wait for me".
I can honestly say I did not push once, and although it was uncomfortable, I didn't have one graze/stitch and after he was born was up within minutes feeling like I could run a marathon! I felt amazing:) It was the most overwhelming, brilliant moment of my life and if I had to do it again tomorrow, I'd be trotting in:) There is alot to be said for not feeling that fear. I'm actually quite sad I wont' get to do it again (medical reasons say I shouldn't).
Good luck, go for it and enjoy:)
