pregnant or not pregnant

okay guys i need some help lol. My period is 8 days late ( i’ve never been late before). I had unprotected sex a couple weeks ago and me or him are not sure if he pulled out being that we were both drinking. I’ve also been spotting 2 weeks prior to this ( never happened before). I took 2 pregnancy test and both were negative so i’m not sure what’s happening. what’s the best thing to do now?
