Am I gonna get pregnant?

So me (F18) and my boyfriend recently had sex unprotected and even though he pulled out before cumming, I’m still having this constant thought on whether i might be pregnant. I don’t know if I should be looking to get pills or plan b medication or whether I should just wait it out until I get my period?

I’m expecting my period next week and currently I’m cramping so I hope I’m on my period but im still freaking out on what to do.

I know we should’ve had condoms on that day but it just happened in the moment and now I’m so anxious.
