Real quick round up

• We've kind of known that menstrual blood contains stem cells, but scientists are always learning more about how those cells can be used to treat disease. In the meantime, there are mail-in menstrual banks where you can donate and store your menstrual blood. (For $499 + $99/year, I'm not exactly sure why you would, unless you're soon approaching the age where the well runs dry, so to speak..)
• A pretty awesome description of what PMS is like for one woman. Exceprt: "A black hole of emotions where sad and happy, tired and energetic, talkative and anti-social all meet and penetrate one another, forming a blob of nothingness. Yeah, I kind of feel like that. They’re all inside me, yet I can produce nothing. It’s like a sharp, involuntary intake of breath seconds before what you THINK is going to be a massive, super satisfying sneeze and… nothing." (PS, that's also where I found this picture.)
• I'm sad there is a market for products like The Va j-j Visor. Also I hate the word va-jay-jay. 
• Did you plan your wedding by your menstruation date?
