You can't stop the flow, so where do you go?
Before and after the Medieval-era in Europe, women’s blood was seen as unclean for men to touch which led to some crazy inventions and ideas. Women of this time may have had far less periods anyway due to less nutrition and less body fat due to physical labor. They hit menopause in their 30s.
“On the Rag”
This is the time from which we got “on the rag.” Women would use either scrap cloth or wool to put in panty-like garments or to put inside of them. But wool repels liquids, so the advent of cloth was quite the revelation.
Renaissance-era European women were considered very unclean, but they had the foresight to create “ragbags” with bits of cloth or cotton that they would wad up and tie with thread to place in the vagina. They would sometimes tie it to a long thread that they would then tie around their thigh to keep it from going in too far.
When women stopped menstruating, people thought that they had a backup of blood within them and were even less clean.
