About 1 1/2 to 2 weeks before the day I was supposed to get my period I started having what I thought were symptoms of pregnancy. I was nauseated, major headache, swollen gums, metal mouth and fatigue. I took a pregnancy test about 6 days before my period, negative. Took another one 4 days before, negative again. Took a last one today (the day I was gonna get my period) and still negative. A few hours later, my period came down, not as heavy as usual, but with cramping much much worse than ever!! Can I still be pregnant?
