I took a pregnancy test at my doctors office and it cam back negative; however, she still thinks I am pregnant, because i have been having headaches, nausea, and cannot be around certain smells. On Saturday I started having spotting that was pinkish and brown that lasted til Sunday, but on Monday it got heavier like my normal period would be. I still get that nauseas feeling but it doesnt last long, and teh headaches have been rare. I have to scheduled blood test on Thursday. CAn I still be pregnant?
