I have never had my period last more than 5 days. I am on thé 13th day and still spotting, should i be worried?

I’m 26, very athletic, I do not take birth control, my period has normally been consistent. I am currently abstinent because my bf and I are long distance. After the 5th day my period stopped but then I woke up the next day with bright red spotting as if it was beginning again. Now I am supposed to be I my ovulation and the spotting has gotten faker, almost like a purple. My body does not feel different but I am concerned. Any experiences with this?
