Hello, Im 20 years old. Just recently a week before my period is due I've experienced small amount of brown discharge, I could wear a liner and it have nothing on it by the end of the day. It only happens sometimes when I wipe, its never happened to me before. Ive only had two sex partners, Ive had a pap in jan. 07 and everything was fine.I have a period every month the only thing is that the length of my cycles varies. I go to the doctor this week I just want extra advice. Could someone help me to understand what the brown discharge could be?
