Menstrual cycles can be baffling, and that's why I really want to make a special poster explaining this special time of the month, mostly so I can justify to my poor husband exactly why I am feeling totally insane. "It's not me, honey, it's the progesterone spiking," or, "Can you understand now why I'm being a total bee-yatch? I've got at least five different hormones coursing through my body right now. I'm on drugs." Marvel at the leutenizing hormone! Be amazed as the estrogen takes a nosedive right before ovulation! Check out the egg as it takes its long journey through your reproductive system! Anyway, check it out and give me feedback -- calling all OB/GYNs! Editors! Anatomy nuts! Sex educators! -- before I send this thing to the printer. I know it's a little crazy-looking, design-wise, but then again, so's the menstrual cycle.
