Period Late 4 days... when to panic?

So my period is late. my body feels like it’s about to get a period because I’m moody and I have light cramps (my usual pre-period vibes). When I made the mistake of asking google it says that can be a sign of early pregnancy. Now I’m paranoid. I’ve had sex regularly this month and I use the pull out method (we use condoms when I’m ovulating and it’s worked for a year and a half). Has anyone had this before? What happened, did you get your period?
