The last taboo: Helping women and girls. Period.

In this special edition, we take a look at the last taboo when it comes to women's health: menstruation. We report on how ad agencies and public campaigns are forcing us to realise that periods are not a dirty matter. We also talk to Jennifer Weiss-Wolf who's leading the charge in getting a more equitable menstrual policy in America. Plus, the women in Madagascar who are highlighting the health and economic costs of not having pads and tampons in poorer countries such as theirs.
