Idk what’s going on?!? Opinions needed!!

No clue if it was AF or not. I was sexually active before, during, and after fertile window. AF was due may 27th AF is very regular. I was late five days the fifth day that night I had some spotting and it was only when I wiped I never needed a tampon or pad. It lasted for four or five days. Should I count that as AF or should I test??
