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.
Best Answer: Hi there, When females reach reproductive age they begin having periods as part of their menstrual cycle. When a girl has her period it means that her body has reached the stage in her cycle in which it sheds the lining of her uterus. Once a month the ovaries release an egg which travels to the uterus; the uterus builds up extra lining in preparation for pregnancy.
