1 week before my period was due I started spotting this brown discharge for 6 days. It barley filled a panty liner. I'm 7 days late now and all pregnancy test came back negative. I never been on birth control before, I know that can cause an irregular period. This never happened to me before. My symptoms: constipated, bloated, a lot of clear discharge now, and frequently using the restroom. Has anyone ever turned out pregnant after negative results ? I'm confused. Please help!
