Every year, since I was 12 (when i first started), I had the same problem. I only have a period 3-4 times a year instead of the once-every-month like most females... When I first noticed that, within the first few years I started, I told my mom and she said that with time it would get better and I would start to get regular... But now I'm 19 and its been the same so far... What's wrong with me? Is this normal?

Which country do you live in?
Have you been checked for STD's?
Also might be an ovarian infection.
Best to see a Doctor of Gynecology
