When filmmaker Diana Fabianova reached puberty, she found herself irremediably trapped in menstrual etiquette. She carefully hid the evidence from her father and brother first, and later on, from most of the other men in her life. And no matter how bad she felt, she pretended she was fine.

Not quite. Something in her was reluctant to accept and suffer in silence. Why did the sign of what all societies consider a blessing -- women's ability to give birth -- happen to be described with names and expressions like "the curse" (in England), the "English war debarquement" (in France), and "to be on the rags" (in the U.S.)?
