I'm 15 years old. I had my first period in my whole existence when I was 10 years old. I haven't talked to any doctors about my condition yet. Eversince I had my first ever period, my period is not heavy or average. Everyday, I only have a few drops on my napkin and my period can lasts a month. It was always like that until I became 13 years old. When I became 13 years old, that was the time that I had the "moderate" period but it also lasts a month. Now that I'm 15 yrs old, I also have "light" period for a week and then "moderate" period for a week too and "heavy" period for days but not in a week. I also have the "light" period to end my period. So it means, my period until now can last to a month. I know that my case is not normal because I have read books about a "normal teen's period" and I feel like I have problems. My mom knows about my case but haven't bring me to a doctor.
