I'm almost 16 years old, and I've had my period since I was 11. The past four or five days there has been this brown discharge on my panties. It doesn't smell bad, and it doesn't hurt, but today, I noticed it hurt a little to go to the bathroom, and when I wiped there was just a tiny bit of blood along with brown discharge. I've never had sex, but I've done other stuff. My next period isn't supposed to start for another week and a half. I'm really scared that I have an infection or some other disease. Should I talk to my mom since the discharge isn't going away? Before I got my first period, I talked to her a little bit through letters, but that's the last time we've talked about this stuff seriously. How do I talk to her if you think I should?
