So 3 weeks ago I noticed that my breast were really sensitive, followed by nausea. So I figured I was pregnant, then about a week ago right before I was suppose to get my period I took a test it was negative. Sunday I started cramping and got my period, but it lasted 2 days, then the next 2 day was spotting. I took another test and it said negative. I was wondering maybe because it was at night time. But my question is why am I still having pregnancy symptoms?
