I have engaged in sexual intercourse with my boyfriend and he has used condoms as protection. My period was due on Sunday. On the thursday prior, when i went to the restroom i noticed some brown discharge. On Friday i started bleeding. The abnormal part for me was that i did not get any cramps as i regularly do. On Saturday morning there was a little brown discharge but no bleeding. Usually, the 1st and 2nd day are the heaviest for me. My period usually lasts about 4 days with some discharge on the 5th day. My period lasted about one day and a half. I took 2 pregnancy tests and both said negative. I have been feeling dizzy for the past week and a half. And this week i have felt more tired. Is there a possibility that i am pregnant?
