Your menstrual cycle is your fifth vital sign—a barometer of health and wellness that is as telling as your pulse or blood pressure. Yet most of us see our periods as nothing more than a source of inconvenience and embarrassment.

The reasons for this are vast and complex and many are rooted in misogyny. The fact is, women the world over are taught the bare minimum about menstruation, and the messages they do receive are negative: that periods are painful and gross, that they turn us into hormonal messes, and that they shouldn't be discussed.

By examining the history of period shame and stigma and its effects on women’s health and wellness today as well as providing a crash course in menstrual self-care, Heavy Flow aims to lift the veil on menstruation, breaking the ''curse'' once and for all.
