Im scared i could be pregnant or not and I’m paranoid

Today I went over to my boyfriends house and made out . He didn’t pressure me but he insisted on fingering me . The question here is , is it possible for me to get pregnant from fingering. I’m not entirely sure but he had pre Cumed before . But we are not entirely sure if it got on his hands . I’m also 4 days into my fertile days so could that affect anything. Please don’t criticize I’m genially scared .
