So I have been on birth control, Lessina, since November but two weekends ago I forgot my birth control at home while I went to my friends, I thought nothing of it because my boyfriend and I didn't have sex within a week period. And I thought I got my period on Tuesday and its still just brown and its way too light to be my period. . . Whats wrong with me? Like could this be from my birth control or could I be pregnant?
