There are more guides out there to getting your period than there are days in your cycle, but what about living with this uninvited monthly visitor? When Hannah Witton started documenting her journey coming off the pill and re-getting her period, she wasn't anticipating the reaction, from people of all ages, talking about it would bring. It exposed a glaring gap - the resources and the spaces to talk about periods just aren't there. And with more and more research showing that your period and your hormones can affect literally every area of your life, this is a problem.

The Hormone Diaries draws on both Hannah's own experiences and, through crowdsourcing on her platform, those of her fans too. It looks at the cultural differences in how periods are treated around the world and includes space for readers to write about their own experiences, creating the definitive period self-help book 50% of the world has been waiting for.
