Lost my virginity

Y’all my boyfriend and I have been dating for almost a year (11 mo) and I’m 18 gonna graduate this spring :) anyways, we had sex a few days ago for the first time and we went at it until he came and then he changed to a clean condom and we went again, I’m not on the pill but should I tell him we should wait or are we okay doing what we did? I love him and it was amazing but I’ve always been very paranoid about getting pregnant because my mom had me in high school but they didn’t use any kind of protection
