I am on the bcp avine and I have brown discharge, are the pills the cause? I have a fibroid and cysts as well. Please help

Do you mean. Aviane as it says in your medications? Sometimes when on these pills for a while you don't build up much of a lining and all there is to discharge is old blood which comes out as dark brown. Doubt your cysts or fibroids play a part. If it is a continuous discharge get it checked out. Could you have left a tampon inside?
