At least according to the newest ad for Kitadol, a menstrual pain reliever sold in Chile.
According to The Viking Network, Viking women retained property and inheritance rights after marriage, plus the right to divorce a husband who mistreated her or their children, insulted her family, or failed to be a good provider. These are considerably greater legal rights than most women had in that era (approximately 800-1050 CE).
I can think of worse metaphors for menstruating women.
