If my bf came on my stomach, and he wiped it after, washed my tummy with soap, is there a chance of me becoming pregnant?

Also, I was on my last day of period. A week after, he touched me but we can't remember if he had semen on his fingers before doing that or not and it was probably dry because he had his pants on the whole time. I still have two weeks until my next period but I am really scared if I can get pregnant from this. We're both virgins.
