Barely Bleeding
Typically, girls get their first period between the ages of 10 and 15. A girl’s body does not follow an exact schedule. It is common, especially in the first 2 years after a girl starts getting her period, to skip periods or to have irregular periods.
There are two types of amenorrhea. Primary amenorrhea is when the first menstrual bleeding doesn’t occur by age 15. Secondary amenorrhea is when normal menstrual bleeding stops occurring for 3 months or more. Since there are many different causes of amenorrhea, TeenHealthFx suggests that you visit your health care provider for a diagnoses.
If you don't have a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist or contact your local teen health center or Planned Parenthood.
