India travels back to the Victorian Age to probe at the use of the vaginal speculum and considers its link to menstrual shame and embarrassment, particularly in education. India then meets Chella Quint, founder of the Period Positive Movement, and also Professor Chris Bobel, who are the women at the forefront of revolutionising menstrual education both within school and the home.
