I got my period Thursday which was supposed to come Friday. It was medium flow but dark redish. Saturday it completely stopped and I've been spotting since but it's dark blood but when I wipe it's bright redish pink or brown and now my spotting is brown. I usualky have 7 day periods never shorter than that and I've never spotted before!! And my periods are always heavy until the last day or two of my period!! I took a test and it was negative yesterday! Anyone know what's going on?
