I have a very low pain tolerance too, and i've attempted 2 natural births but had morphine both times. I tried to use hypnobirthing techniques the first time, they didn't work for me. I'm not one for relaxing and visualisation. And while it is a productive pain, it still damn hurts. I found it uncomfortable and unpleasant. And to be totally honest, having gone through it feeling absolutely everything, if i ever had a third i wouldn't want to feel it again. I didn't enjoy either birth, particularly because they were so painful, and it created a very negative mindset, and particularly the second birth i believe a factor in my PND. So if there was ever a third labour for me i would go all the pain relief i could get. I realise this isn't a popular choice, but i'm just being honest!
