Facts to Know

Puberty lasts for several years. It is the stage of your life when your body is changing from the body of a child to the body of an adult. Hormones, which are natural chemicals in your body, are orchestrating these alterations in your body.

During puberty, one breast might grow larger than the other; but don’t worry, if there is any difference in size nobody will be able to notice. Once your breasts start growing, the differences will most likely be so slight. And your breasts will even out before they are finished developing. But if they don’t, no need to worry since many women’s breasts don’t match each other exactly.

It might take a while, perhaps even a year, for your periods to become regular every month. During the first year, your cycle may be as short as three weeks or as long as six weeks. Even after your periods become regular, exercise, stress, or a change in diet could throw it of track. If you are sexually active and skip a period, talk to your health care provider immediately.
