So I am on on NORG-EE (oral contraceptive combination pill) and this is the 6th month I have been on it. I have been experiencing very light brown spotting/discharge the last three days. I had protected sex (condom) on the last day of my ovulation(monday 11/28) and the spotting happened on the 5th day after I had sex(saturday 12/3). I have also been stressed out due to school. I do not expect to get my period until the 15th of the month. I read that implantation bleeding does not occur until 3-7 before menstruation, so is the spotting due to stress and the pill ?
