So for the past couple months my period have been nothing but normal. Very light, and short. Well for i would say the last three weeks i have been bleeding. Not heavy, and not constant. Some days it dark, some days its red. Its never enough to change a pad more then one a day. Sometimes i think its gone then comes back, more so when i am working out. I have tested and its negative as i figured it would be.... but what else could it be?
