Spotting?

Help!! So I just got off my period on the 31st and on Friday (the 3rd) I noticed blood when I went to the bathroom. This was a good amount of blood so I naturally freaked out a bit since this has never happened to me before. Tonight(the 5th) the same this has occurred. Can this be normal signs of me entering my fertile window? I am taking an ovulation test and I know I’m ovulating soon. Has this happened to anyone else?
