Am I Infertile?

Me & my bf have been together 3 years, we've been sexually active for 2 and we've only used condoms like twice as far as I can remember. And for like a year now he has just been cumming inside of me and I haven't gotten pregnant😩🤔. I don't want to be but it still worries me whenever I want to have kids💯. I don't think it's him because I've had one other sexual partner and they also did the same and I never got pregnant. I've never had an STD/STI and my periods are regular and I'm overall pretty healthy. I want to know if I'm overreacting or what😕 I read somewhere that 1 in 6 young people think they're infertile. Please anything helps😊
