But our periods and our hormones affect every area of our lives - so I am done with scuttling to the toilet with a tampon up my sleeve.

From first periods to first coils, pimples to hot-water bottles and PCOS to endometriosis, The Hormone Diaries is your essential companion on the hormone rollercoaster. Filled with Hannah's insights, fascinating research and those priceless crowdsourced stories, it's the reassuring hug we all need.
