My period stopped four days ago. It was also a period that was 8 or so days after I expected it. I took a pregnancy test the day before I started and it was negative, obviously. But I just went to the bathroom and saw blood when I wiped. When I got up, I looked and there was some red...stuff..on the bottom of the toilet bowl. I dont ever really bleed after my period. Im cramping a little on my left side too. Any ideas??
