Can A Shark Tell When You Are Menstruating What Happens When You Hit A Shark's Nose?

What happens when you hit a shark's nose? - can a shark tell when you are menstruating

If a man attacked by a shark. What happens when they reach the shark-nose? I read in a book, fear of sharks and fly, but I did some time ago. I can not find anything online. Can you tell me? Thank you!
