No? Well, I can't be too sure, I'm not a doctor...yet. But anyway, you're young, periods tend to be irregular in adolescence. You might consider a gynecologist. I suffered through metrorrhagia at one point (a light, intermittent flow) between cycles about 4 years ago. I was diagnosed with high levels of testosterone and hirsutism (I know, gross), which may be linked to PCOS. We're honestly not really sure, so I see an endocrinologist in addition to a gynecologist. I was treated with birth control, which really did help, except for the hairiness. sweatdrop Then my mom read about triclosan raising testosterone levels in animals, and decided I should avoid it. Knock on wood, but my periods and testosterone levels have been pretty regular since avoiding most triclosan.
