for the past year my period was pretty regular... well sorta, it was coming every other month, which to how my cycle has always been, is regular...

since october 2008 around the 22nd or so i started bleeding, which i thought was my period since the last one had been in august.

the bleeding has never subsided. its been light most of the time, and then for a couple days it'll be kinda heavy, sometimes its brown, sometimes its bright red.

i just turned 24, and have never been pregnant before...

does anyone know what this could be?
