Sometimes if you're a runner or very physically active, have a lower weight for your height, vegan, or have bad eating habits your period can come later. However, my friend didn't get hers until she was almost 17. It wasn't because she was underweight, nutrient deprived, or had anything wrong with her. Sometimes it just happens. Now if you're concerned you can see a doctor, and he may do tests to rule out anything. And if you are sexually active you may want to consider a pregnancy test.
awwh bless. your maybe just a late starter thats all. have you spoke to your doctor or school nurse maybe.
Im 15 to and haven't had my period every since July (1-8) and if you been having unprotected sex and. Your period is regular meaning you see it every month you may be pregnant. Or there's a possibility you could have amenoherra some my ob trying to say I have because my preg. Test came back neg. But I have symptoms of me being preg. And I think I am. And that is not a disease its a symptom.
