I noticed too that my pains werent as bad as normal, and my cycle seems pretty regular now as well, which is very odd for me!!!
I assume the way period pains affected me MUST have been dictated by my diet in the past and the fact that now my body is getting all it needs, it doesnt feel the need to rebel against me as much!!!! Just my theory and I'm sticking to it!!
I posted a similar thread a month back. Like you I had an almost painfree period , which was a nice suprise given that its usually quite bad. Whether its the CD diet, loosing weight or not eating rubbish food I dont know, but it was so nice not to be in pain.
