While accepting Oscar for Best Short Documentary for 'Period. End Of Sentence.' at 91st Academy Awards, the film's director Rayka Zehtabchi said, "I'm not crying because I'm on my period or anything." "I can't believe a film on menstruation won an Oscar," the 25-year-old director added. The movie, which talks about the stigma of menstruation, is co-produced by Guneet Monga.
