Is it possible for pregnancy?

I know this sounds stupid..but gave my “friend” a handy, i had my pants on and my underwear. He “finished” suddenly onto my right hand and the floor, a drop got on my pants on my thigh and another drop a little higher,  i could see one drop soaked through onto my brief like underwear underneath, i shook my hand off and Wiped it and dried it off Pretty good with a paper towel. My hand was completely dry. He did not touch me with his hands after just to be safe. I came in and washed my hands with soap and water quickly, and then peed, wiped,  and then washed my hands again. I changed my pants and underwear shortly after. I left them in the basket with my towels for days, and they’re all in the washer now. I took the plan b pill just to be safe because i got nervous about “wiping” not being sure how well i really washed my hands. Is it possible i could have gotten pregnant? Is it possible Washing Pants with my towels it could transfer to the towel and cause a pregnancy? Was wiping and drying my hand completely with the paper towel enough? Help me out. I am paranoid
