Most girls start their periods between the ages of 12 years and 14 years, but some start earlier or later. When you first start having your period, it may last only a few days. Your first few periods may be very light. You may only see a few spots of reddish brown blood. Anywhere from 2 to 7 days is normal.
No two girls' periods are exactly alike. Periods can last from 2 days to a week. Some girls have very heavy periods with monthly cramps, and others have much lighter periods after the first couple of days. It also takes a while (usually 12 to 18 months) for a girl's period to become regular after her first period. You may get your first period and then not have another for a few months. As you get older, your cycle will become more regular â usually between 21 and 34 days in length. The amount of blood you lose during your period can vary, too. It can seem like a lot, but typically it's only about 2 tablespoons.
