If you have time, start by letting it settle. Put the water in a tall container and leave it for 12 to 24 hours. Carefully dip or pour the cleaner water at the top into another container. Clean the water as you put it in the new container by running it through a filter. The easiest filter is a coffee filter. If you don't have a coffee filter, use a paper towel or a piece of clean t-shirt material or similar cloth. Change the filter whenever it gets visibly dirty. Once water is filtered, it is fine for using to clean things like clothing and floors.
Menstruation(men-STRAY-shuhn) is a woman's monthly bleeding. When you menstruate, your body sheds the lining of the uterus (womb). Menstrual blood flows from the uterus through the small opening in the cervix and passes out of the body through the vagina (see how the menstrual cycle works below). Most menstrual periods last from 3 to 5 days.
This usually happens between ages 12 and 13, but menstruation can start earlier or later. During a menstrual period, there are two to three days of heavier bleeding with two to four days of lighter flow. Menstruation happens to all girls, so try not to be embarrassed in learning more about it. Talk to your mom or an adult you trust about having your period. During your period, you'll need to wear a sanitary pad or tampon. Your mom (or other adult) can purchase these products and show you how to use them.
