I'm 17 years old, and I've never had sex before. My periods are very irregular and they come pretty randomly, in fact, I usually only bleed a little and then the rest is brown. I have frequent itching and the discharge has an odor. It has been this way for quite sometime now. I'm not sure if this is an infection, and I've never been to a gynecologist before. I haven't talked to anybody about it, just because I'm not really sure how to approach it or anything. I think I might have a hormone problem because I was premature when I was born and that has seemed to cause many of my developing problems. I just need an idea of what is wrong with me.
