worried ab pregnancy


hi so i recently became not a virgin and the first time i had sex with my boyfriend we didn’t use a condom and i’m not on birth control but he didn’t cum inside me or precum inside me but i took plan b anyway. i got my period and i was so happy but we recently had kind of sex but i told him to pull out because he wasn’t wearing a condom again and i didn’t wanna have to worry. he precame before he went inside me and never came after. should i be worried about anything ?
