I can't rave about natal hynotherapy enough (UK version of Hypnobirthing). I had a lovely labour and still look back on it as a really positive experience despite a long labour and a few complications afterwards.
If you can't afford the course try and buy the book by Maggie Howell as well as the CDs (everything in it is taught on the course). I was given a complimentary one as I attended the course but the book is a really good read with some useful techniques. Some really basic things discussed (ie how as mammals we are born to give birth naturally etc) and also how medical intervention is so common practice these days.
I was in slow labour for 5 days and then hard labour for 10 hours on the 6th day but honestly, that week just flew by to me and the 'hard' labour was exhausting but felt like 3 hours not 10. I have some of the happiest memories with my DP whilst in slow labour and I put that down to being relaxed, content and confident that my body was doing what it should naturally.
With Natal Hynotherapy, they don't project that your labour will be easy or pain free, but it does give you 'extra' tools and techniques to use whilst in labour to help you relax.
The book should also be given to your DH/DP to read - my DP was amazing during labour, even the midwives commented on how helpful and useful he was and how he understood what I wanted and when.
All the best with you birth somanystripes
