Honestly, for me, it was more uncomfortable than unbearably (sp?) painful. I had OHSS during IVF and that hurt a truck load more than labour. If you are excited and not scared, thats a pretty good place to be mentally imo. Remember the mantra that 'Fear= Tension= Pain', I think that is something that really helps get you in the right 'place'. Good luck, and I hope your labour is everything you hope for
