I am a girl aged 15 years old. I started my periods when I was 13 years old. Now my problem is that I haven't had my periods for the last four months. I am a virgin and have never had a boyfriend. Is there something wrong with me? My friends say that I am infertile. Is this true? Please help because I'm scared that maybe I can't have children.
