Is it possible that I am Pregnant?

I (22F) had a steamy afternoon with my boyfriend (21M). We were on the mood and we got naked. I gave my boyfriend a head and he came. He touched his come but wiped it off on his thighs. Then we started making out again and he started rubbing me down there with the same hand he touched his come with. After we realized what happened he immediately washed his hand.

This happened on my 4th day of period. No penetration occured. He just rubbed my vulva area but mostly the clit part.

So is it possible that I can get pregnant?
