please 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 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
