Has anyone got pregnant from pre-ejaculation?

You can only get pregnant from intercourse (coming) I know for sure. But is it possible to get preggo from pre-ejaculation? I read on good ol google its possible but doesn't usually happen. But I have anxiety and I keep freaking out because my period is late. I have no symptoms or signs of an upcoming period. I asked my friends and they say I'm freaking out and I shouldn't worry. It should just be a late period. & well I believed them but idk. I need a broader opinion and or statement. Can someone please help :(...
