Can I get pregnant by fingering? (TMI)

I was giving my boyfriend a blowjob at first and he decided that he would finish off by yanking himself. When he was about to ejaculate, I immediately swallowed his semen. Afterwards, he cleaned his hands with rubbing alcohol (isopropyl alcohol). Then 5 minutes later or so, he decided that he would finger me so he cleaned his hands with rubbing alcohol twice then fingered me. I know this may sound stupid but, Could I get pregnant from this?
