Ok well I'm 13 and I haven't had my period in over a year. I have only had my period 3 times. Then it stopped for over a year.. is their something wrong with me. What should I do? Would it be necessary to see a doctor? Help

There is nothing wrong with you, your period is just starting to develop (as werid as that sounds) but if you're uncomfortable with it, you can always go to a doctor.
