im scared

So I let my boyfriend fuck , he had a condom on but it ripped , so I sucked him off , taking away any pre cum or anything that could be there , and he squeezed some of the pre cum that was there. He did like 3 strokes and that's it.  I'm 2 days late on my period , and in kind of nervous. I can't be pregnant , do you think I'm pregnant because of that ?? Maybe I'm over thinking it and maybe I'm just late but i just need advice someone , please help 😭😭
