I am on birth control and am very good at taking it so my ex and I never used condoms. I have been experiencing a light brown discharge the past week. It goes for a day and then quits. I normally would think its just my period but I take 3 months of birth control before taking my sugar pills because of migraines I get during my period... I shouldn't get my period for another month. I have taken two pregnancy tests and both came back negative but I am still having a brown discharge. Could I be pregnant?
