Part II, because we care. (Inspired by Flitmouse)
Sorry Flit, but after you sent me the link to the video about home made tampons, I had to do a little further investigation. The menstrual cup sounds so much safer and healthier, plus you could easily store five or six of them and have a lifetimes supply tucked away.
I think they are more widely used in Europe, but I would recomend getting a couple and practicing so you have one less thing to worry about while trying to board up the windows.
