With chapters in over 40 US states and over 20 countries, PERIOD. activists have made strides for menstrual equity in their communities around the world.

Chapters work to advance PERIOD’s mission of eradicating period poverty and stigma by creating action plans that employ our three pillars of service, education, and advocacy in their own community!
