Is it possible?

Hey, so this is probably absurd but I am a really anxious person so I cannot stop worrying about this. I have never had penetrative sex, but my boyfriend's penis has been on and very near my vagina, and I know sometimes, though rare, you can get pregnant from pre-ejaculate. My period is usually fairly regular, if not that it is only a few days late typically. I am now 12 days late and I cant stop worrying about it. Should I take a test, even if it's just to calm my anxiety? 😅😅
