This possible?

So I gave my boyfriend a bj and he came and such, I swallowed it all okay and probably about 4 hours later, I was at home and I touched myself but I wasn't sure if I had anything on my hands from him so I washed my hands off with soap and water and then used hand sanitizer( just to be safe) and dried my hands off and then just rubbed the outside of myself. Is there absolutely any chance of pregnancy there? Probably not but I get worried easy. Thank you (Glow also says I have a 3% chance of pregnancy that day)
