I'm posting this link because it probably says something about the FASCINATING influence that the moon has on women with respect to their menstrual-cycles.

I'm soon going to be releasing a thread all about the moon, myself, and have been appreciating the large ammount of information that has been coming out as-of-late.

LINK: Thread: Are women doubling up on menstual cycles lately?

I don't yet know if this post actually referrs to the moon as having a significant effect on female menstruation, but presume it does as it is a fairly well-known phenomenon.
