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.
One day, you'll begin to bleed from your vagina, and that's your period. It means that your body is healthy and normal. Most girls have their first period when they're between 9 and 15 years old. Your period may start around the time it started for other people in your family, like your mom or sisters.eriods usually last about 3-7 days, but may be slightly shorter or longer. During your period, a bloody fluid comes out of your vagina. The heaviness and color (more red or more brown) of the menstrual flow changes from the beginning to the end of your period.
