Pregnancy Test

Okay, maybe this is a dumb question but I've never been this freaked out about being pregnant, so Saturday night/Sunday early morning, I had sex. He didn't cum inside of me, but it was unprotected sex and I know you can get pregnancy off of pre-cum. My period is supposed to start in 12 days, should I just wait until my period to see if it comes or take a test sooner? Also, when should I take the test, if that's the advice y'all give?
