Period positivity starts with asking questions.

This informative, irreverent and absorbing book covers all your period-related questions - why they're taboo (and needn't be) and how to navigate the whole bleeding thing, from first periods to fertility, euphemisms to uteruses, menstrual products to menopause.

Period Positive movement founder and menstrual researcher Chella Quint's answers are frank, funny and fascinating.

Let's get period positive. It's about bloody time.
