So when I was a freshman in high school (about 14 years old) my grandma put me on birth control, to get rid of my irregular, heavy, periods, and to clear up my face a bit. I've been on Yaz/Yazmin since then, and now I'm a 16 year old sophomore. About three weeks ago, I started having a weird bleeding. It's not red like a period, its brown and I believe there to be some discharge. I'm confused, is there something wrong with me? Additional information, I have never had sex so there's no chance of me being pregnant.
