6 days late after plan b pill

Douda

So I had sex on may the 13th(no internal ejaculation, 3 series of penetrations that lasted less than two minutes plus I wiped off the tip to remove any precum) the morning after, I took the ´emergency’ or ´plan b’ or ´ morning after ´ pill. I was supposed to have my period on may 24. I’m 6 days late. What should I do?
