Puberty: Irregular menstrual cycle

When a girl begins to menstruate, she often has irregular periods or amenorrhea (one or more missed menstrual periods). This is normal! When it becomes regular, a menstrual cycle lasts about 28 days, but it can be as short as 21 days or as long as 35 days.

During the early years of menstruation, it could be that the menstrual cycle has not quite developed and that you have irregular periods; or, on the contrary, it is very predictable. Some girls know that their period will come every 28 days, and you can depend on this timing. Others may have two cycles of 28 consecutive days followed by a delayed period, and then have two periods quickly, one after another. As we age, menstruation normally become more regular, which will help you to predict when your period will come.

Create a record of your period every month. You can put it on a calendar with a red dot, or keep a special calendar to track your period and any symptoms you might experience in the event that you want to consult a health care professional about your cycle.
