heartmoonshadow, I had terrible period pains too.. I really found TENS helped in labour, I was sceptical but it really really worked and was effective, cutting about 30% of the pain.
I would inform yourself about the epidural and make sure you're going to a hospital which has it available readily, but try TENS and books like Birthing from Within and Ina May Gaskin's Guide to Childbirth, both I found very very helpful.
If your birth goes normally/fast, it's probably better to try and go with it, but if it's dragging on or you have a very long pre labour, I would definitely take the epidural.
I am a really really big coward and never would have believed it was possible without pain relief, and indeed it was really painful at the time, like coming up against a massive precipice and looking down, BUT about 3 hours after the birth I had genuinely, totally forgotten it and now, 6 weeks on, that pain is totally irrelevant to me, I was not traumatised in the least. Friends I know who have been traumatised have not been so through the pain itself but through being treated badly or insensitively by medical staff, or through things going badly wrong. The pain of childbirth per se does not traumatise you, but something like a forceps delivery can.. You can maximise your chances of a good delivery by staying upright etc. I read EVERYTHING during both pregnancies, and was so glad I did, as I was informed about what procedures led to what, and what I could do to improve my experience, including trying to find the best hospital near you etc...
don't worry and best of luck!
