Late periods and pregnancy

My periods are already 9 days late...I had my last period on 13may...that lasted 7 days so we could say I was menstruating from 13-19may..now I had a bit of intimacy on 23 may..more like just rubbing he did have a bit of precum....now I m worried if I am pregnant?????or so....and also i might have accidentally wiped out the cum and touched my vulva with the same cloth..Google can't stop making me feel I am pregnant...any viewss
