The BBC broadcaster Emma Barnett was the first person in the UK to announce she was menstruating on live TV news. Now she has written a call-to-arms manifesto on why we need to destroy the ludicrous stigma around periods. In the second part of our True Blood series, Emma talks to Kathy about the history of the taboo of periods, the stories women shared with her for the book and the new wave of activism dedicated to normalising menstruation. Emma also talks about being diagnosed with endometriosis just three years ago and why an inability to talk about periods contributes to so many people suffering from the debilitating disorder in silence.
