What do you call your period?

I'm in college and my friends and I were talking and eating insomnia cookies (obviously a must have every Friday night)

I digress, ANYWAY we got to talking about our periods and one of my friends was like oh my gosh Helen has been a bitch this week and I was like Helen, who in the heck is Helen?!

Then my other friend was like I can always tell when Helen takes a visit, because Gerty likes to show up unexpectedly for a surprise visit. At this point I was utterly confused and my friends told me that they named each other's periods: one was Helen and the other was Gertrude aka Gerty 😂

So I wanted to get in on the action and they helped me and my twin sister name our periods: Ramona and beezus (mine).

What do you guys call your periods??
