When a girl starts her period, it means she has reached the age of sexual maturity that means she is old enough to get pregnant. When a girl is old enough to get pregnant, the uderin wall strengthens to protect the womb. But if no sperm is injected in it (if you don't have sex), then there is no need for the uderin wall to strengthen, so the extra blood cells that it built up are bled out of the vagina. That is your period. It usually does this about once a month.
