So I am 17 and I never had sex or had any kind of sexual relationship with a guy. I should've gotten my period 9-10 days ago, but instead I got some kind brown discharge. It was light in the beginning, but then it got stronger. Then it wasn't only brown discharge, it was kinda mixed with fresh blood. I thought it was my period but the brown discharge never ''left''. So now 9-10 days later I still have some kind of bloody/brown discharge. What is that? I read somethings online, and I saw somewhere that some medical conditions or medications can cause it. I had my tooth treated in the past 3 weeks, so could the medications they used contribute to it? I know it sounds silly but I am really starting to freak out, cause everything I read said that I might be pregnat, even thought I know thic can't be cause I never had sex. I will really appreciate your answer. Thankyou.
