Definitely need opinions

So I had sex like 52 days ago. I took a plan b the night of because the guy I had sex with was an idiot. I had a really small mini period, alot smaller than mu usual but way to big and red to be spotting or implantation and it lasted 5 days. Ever since i’ve been taking pregnancy test to see if iI was pregnant and they all said no. Now here we are, 11 days lat, and I don’t know what’s going on. I took yet some more pregnancy test (I took one like 2 days ago) and they’re all saying no. Now that’s a good thing but where is my period? Any thoughts or advice ?
