Just wanted to offer another perspective. I used hypnobirthing (although I didn't have time to care about listening to my tracks, just used the techniques I had been practicing) for the delivery. I had a smooth, quick and relatively easy med-free birth, but ended up retaining my placenta due to improper cord traction and required an emergency manual extraction of my placenta (aka, an OB was called in to reach up and get it.)
I opted not to take the pain medication that was offered. The procedure was extremely painful, more painful than anything I have experienced. Labour was a breeze comparatively. I most definetly required my hypnobirthing skills to get me through, but mostly as a way of focusing on something outside of the pain. Hypnobirthing and the concept of using your mind to manage pain was invaluable in my natural birth.
GL with your upcoming birth and baby. My little guy was also due Feb 20!
