Tampons in men’s restrooms? Activists, schools and businesses are serving the menstrual needs of those who don’t identify as women.

At the first National Period Day rally in Chicago, more than a hundred supporters gathered at Federal Plaza to champion better access to menstrual products and an end to the social stigma that often surrounds menstruation.

Among the sea of handmade signs dotting the crowd, at least one specifically highlighted the menstrual needs of transgender and other nonbinary folks — a group often overlooked in the movement to make tampons, sanitary pads and other menstrual hygiene items available to everyone who needs them.
