Your first period may last from two to seven days. Then, there might be 30 to 40 days, or even longer, before you have another period. Your next period might be heavier or lighter than the first.
Don't worry if you have your first period and then don't have another for four to six months. This irregularity is normal at first.
Your periods should become regular within two years after you start menstruating. Some teens have a 28-day cycle; some have a 24-day cycle; others have a 30- to 34-day cycle. All of these are normal. If your period is shorter or longer, or if your period does not become regular after two years, see your primary health care practitioner.
It is normal to skip a month, especially if you have been ill or under stress. (Tell your health care provider at once, however, if you miss a period and are having sexual intercourse. Even if you are using effective birth control, pregnancy is a possibility.) But skipping for more than one month once your periods have become regular is another reason for a doctor visit.
When your period becomes regular, mark the date on your calendar for several months ahead. This will remind you to have tampons or pads on hand and help prevent accidents.
