If women dive while menstruating, will there be an increased danger from sharks?

It is true that sharks have a heightened sense of smell and that they are attracted to the smell of blood, but according to the Divers Alert Network (DAN) many species of sharks are not attracted to this type of blood.  Sharks are also generally attracted by sound long before they smell blood.  There is no evidence to show that shark attacks increase for women who are menstruating.
