Is it bad if I get my period twice in one month? Why does this happen?
Shoshanna*

It's often normal during the teen years to have irregular periods. When a girl's period is irregular, it might come more than once a month or only come every few months. Some girls find they get their period more than once some months, then they might not have another for several months. This is the body's natural way of adjusting to the changes that come with growing up.

Your cycle should settle down within a couple of years of getting your first period. If your periods are heavy, often come more than once a month, or if you've had sex, check in with your doctor or nurse practitioner or visit a local health clinic. Some clotting problems, hormone problems, and sexually transmitted infections (STDs) can cause girls to bleed more.

A checkup can help determine if you need any medication or treatment — such as iron supplements to prevent anemia or antibiotics for an infection. Best of all, getting checked out can put your mind at ease and give you a chance to learn more about your body.
