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

It's 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 may 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 in a couple of years. If your periods are heavy, often come more than once a month, or if you've had sex, check in with your doctor 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, seeing a doctor can put your mind at ease and give you a chance to learn more about your body.
