Can I get pregnant if I give my bf a blowjob then we kissed, after that he eats me out

I have the worst ideas these past few days thinking that I am pregnant after giving my bf a blowjob and kissing him after that. A few minutes later, he eats me out. I have depression and anxiety because I'm a bulimic person and I seek for help. My life depends on this and I regret doing that sexual activity.
