Hey, I just found a great site if you’re interested in the history of menstruation, the colloquialisms that describe it, and the products that have dammed up the red tide through the years. ???? ???? ??? ???? You want a 1920’s Kotex ad? This site has it. You want to know 320 terms that mean menstruation? Look no further! Find it at the Museum of Menstruation and Women’s Health.
