Women should never go outdoors in bear country during their cycle. Bears smell that and go wild. And anytime a woman is killed whilst on that period her snatch is MIA and upon post mortem found in said bear's tummy.
Chow!!!
Remember that bear lover guy/Treadwell. He was rich and was always loitering with the bears..."Oh, I see you went #2. Oh, it's a such good one, sweety. Smells like a healthy one. It's still nice and warm. Oh, you're so wonderful to poop in so perfectly a pile. Like soft serve from the Good Humor Man. Oh."
Long story short that guy got eaten and his gf was with him and unfortunately was in her period. Need I say more?
