Brown discharge is usually left over blood that didn't make it out during your normal period, but it usually happens to me when I start my next period.
You could have an infection. I'm also 18, going to the gyno isn't as bad as it sounds, just make sure you find one that you are comfortable with. Trust me your gonna have to go some day its better to get the first time done and over with. I was scared sh!Tl*ss my first time, and what made it worse was that they wanted the hottest intern to come in to observe it. After the first time it's a piece of cake.

thank you very much. I was all freaking out. So I guess brown discharge is normal. Maybe i'll go to the gyno. It just never happend to me before thats why. I guess I was stressed out and my eating habits changed. That may have something to do w/ it. My monthly period contains brown discharge still so its prolly leftovers huh? I dont think its an infections cus i'm not in any pain and it doesnt even smell either. Anyways, thank you =]
