I am a 21 year old female. I was on the pill for several years when I decided to stop due to non-sexual activity. Since then I have gotten my period every few months now out if no where I've had my period for 3 WEEKS !!! no cramps, it's not heavy at all, but it goes from a brownish to bright red every day! I dpn't have a Dr. as of now I am waiting for it to stop so I can find one and get examined! What could this be? Thanks
