PLEASE I NEED HELP

Pau
Can anyone help me? I just feel so stressed thinking about this for the past few weeks. My boyfriend and i had sex for the first time (im a virgin). We had oral sex and he cum afterwards before the actual intercourse. We didnt wash ourselvea then he told me that it wouldnt hurt so much if we put the condom later then i agreed. After he broke mu hymen he put the condom  and it happened. I just feel stressed thinking if i can get pregnant? We had sex 2-3 days after my period. Please help
