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

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. A period-tracking app on your phone is a great way to see if you period is still adjusting. The more often you use it, the better it is at finding a pattern in your periods. 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 STDs can cause girls to bleed more.

A checkup can help find out if you need any medicine 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.
