I just had unprotected sex 3 days ago and I had my last period 2 weeks before that. My period has always been consistent and regular, and I just got it again today. Its been 3 days since I had unprotected sex and am unsure if I could be pregnant because my period came right after and I'm not supposed to have it for 2 more weeks.It was really random and unexpected. Not sure what it going on but is there a chance I could be pregnant?

Yes, there is a chance you could be pregnant. It sounds like you had sex at a time you are normally fertile. If you had bleeding very soon after, it might be related to the sex rather than be a period.

Wait until the time you would normally expect your period and do a pregnancy test.
