Haven't had my period for over five months. No way I am pregnant. I am not the most active person, I'm chubbier, but no health problems otherwise. Help? I'm 14. It was fairly regular before.

This is something you need to ask your DR as there is so many answers here and without doing any tests, I wont venture to say what is actually going on here so have your Mom get you to your DR to be sure. Good luck
