i need advice

so i’m 17 and so is my boyfriend and he took my virginity a while ago . we’ve only had sex 3 times and each time we haven’t used a condom because we took each others virginity . i know it sounds stupid but just hear me out . i was supposed to get my period today and i haven’t yet . but he didn’t cum in me . i can’t have a kid but i can’t get an abortion because obviously our parents don’t know . and i don’t have enough money for the pill . what do i do .
