I'm about to turn 16, my period is not normal what-so-ever, and I've had sex before. I started getting brown discharge. I don't really keep track of when my period comes and goes. Sometimes it's two months, other times it comes each month. I used protection. My period is very strong and heavy. But the brown discharge is too. I don't know if it's an infection, I tried telling my doctor and she told me it was normal but I want it too stop. -.- yes, it's stressing me out, I don't know what it means. Can anyone help..
