should I be worried?

so I’m gonna be 2 days late, and that’s not really normal for me (since I’ve been quite regular) but I’ve never had sex. But should I be worried about giving my man oral, then making out, and then he went down on me = a pregnancy? I know it sounds dumb and ridiculous but my anxiety kicks me so hard in the ass, it’s a problem.

Kind comments only please, thanks x
