I have been having vaginal discharges that is a brown liquid with an odor. There is normally a light burning sensation, urination frequently, and light cramps. This has been going on for three days. My period was one-two weeks ago, I am on the pill so I do not think it is my period. The last time of intercourse was two months ago, and I have been having my period for many years...So it has nothing to do with just starting out. Any idea?
