I've been calling it Moontime since high school. "That" Time of the Month is also used. Or just plain Period. Although I have called it (during particularly difficult cycles) "God's a Misogynist Prick Event".
I remember coming across a reference to it in the Oz Books (surprisingly) and Dorothy Gale commenting that she wouldn't be able to have a Monthly Visitor because her house is just too small.
One of my friends who is a lay monastic and professionally writes about the spiritual motifs of the Harry Potter universe calls her period "Voldemort" (because it's painful and leaves a Dark Mark).
