All Women Have Periods
All Women Have Periods is one of the most talked-about Documentary movies released in 1979, attracting audiences with its cinematic storytelling and memorable performances.
The purpose of this film isn't entirely known but I suspect it's targeted at the parents with a mentally disabled child who want to educate her about menstruation. It shows what's likely a real family in which the youngest girl has down syndrome discussing periods and the older sister demonstrating the correct use of a pad.
