Preggers

So my bf and I like kinda got it on a few weeks ago, his dick never went in and he wore a condom because we were gonna go all the way but like I wasn’t feeling it so we didn’t end up doing it. We then just kinda like made out and he took his condom off and I know I’m paranoid but I’m freaking out because my period is late and it never is so I’m freaking out that maybe when he took it off he had pre cum and idk what if it touched my vag and I’m pregnant 😂 help is it possible that I can be?
