Spudtastic, it's interesting you should say that... I didn't manage to get onto my local hypnobirthing course (I wanted to, but couldn't get childcare for my twins) but now I think about it...
I only went into hospital because I started bleeding (I had been contracting on and off for a couple of days, but I knew labour still wasn't established yet as my contractions were stronger but still irregular). As expected, I was only 3cm when I got to hospital but was kept in because of the bleeding.
5 hours later I was still 3cm and I then became very despondent and scared that it wasn't going to happen and that I was going to end up with a caesarean because Labour still wasn't progressing. The contractions then became much much stronger and a different midwife wanted to examine me again because I was visibly in so much more pain. But because it had only been 45 minutes since the last examination, I panicked more and wouldn't let her because I was terrified I'd still be 3cm; and the pain was so much worse now, that I didn't know what I'd do if that was the case (because I was on the antenatal ward so couldn't have any pain relief).
I began to lose the plot a bit because everything was just overwhelming me then, and the pain was terrible between the panicking and crying.
I did let her examine me and she told me I was 4cm, so I was taken up to labour ward (6 hours after I came into hospital).
From then on, the pain was much more bearable. I remember saying to OH that I felt much calmer being on labour ward because I knew it meant things were happening, whereas before I had been in pain but knew that I still wasn't 'in labour' so it felt like for nothing. I coped much better after that which I assume is because i was so much calmer and less scared. It certainly wasn't painless, but compared to the pain I was feeling when i was panicking, it was much better.
I then had a quick labour (he was born 3 hours later), so it was pretty intense, but it was bearable by staying calm as much as possible.
The only time I panicked again was when I kept being told not to push because it was 'too early' and I couldn't help it. Again, that was pretty painful as I was being told to do one thing and my body was doing the opposite, so I was trying to fight it and it wasn't happening! I was fine once I knew it actually WAS ok to push and I was allowed to just get on with it (I asked them to examine me and check because I couldn't stop).
