help pleaseee

okay so last night was the last day of my period and i was wearing a tampon. but on the way to my house i gave my boyfriend a hand/blow job. about 2 minutes from my house i stopped and wiped my hands on my jeans but when i got home about 2 minutes later i took my tampon out which i had to kind of go in my vagina to get. but i was wondering if i could get pregnant from that. someone please help
