hi im 19 and been on what seems to be my period thepast month. bleeding everday, sometimes little somtimes a lot. i get no cramps or anything but my breast do hurt sometimes. the blood is mostly brownish/black but may sumtimes be red(very rare). a month ago i went to go get birthcontrol but yet have not taken them because of the constant bleeding. like even when i get aroused or turned on instead of getting normally wet, blood comes out.does anyone know what may be happening, any help would be nice.

p.s i am a lesbian so pregnancy is not possible.
