My menses came during the full moon for most of my cycle. It was great for birth control and also for knowing when I would need some alone time with my crazies. I would tell my DH that I wanted some "quiet time" because I was cranky and he would snicker and say "Oh, it must be getting to be moon time again." He would tease me and call me his lunatic but he always respected my quiet times (smart man!).
