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!

Let's Get Started!

Resources to address period poverty are available to everyone, via our Launch Pad. The Chapter Portal is exclusively for our Chapter Community to connect, and for resources specific for leading a PERIOD. Chapter.

“Thank you so much to everyone who came out to our donation drive to drop off product!”

PERIOD Toledo hosted a product drive to benefit menstruators in need in Beirut, Lebanon in the wake of the explosion in August. Periods don’t stop in crises, and thanks to our tireless chapter members, menstruators will continue to be served where help is most needed.
