5 days late for period

So, 5 days late for my period but I am all these PMS symptoms. I took pregnancy tests (a little too early when I tested) but they were all negative. I had very light pink (could barely see it) spotting on the toilet paper when wiping on the day I was supposed to have my period. We had a lot of unprotected sex during my fertile window (pullout) but we've done that 6 years and only got pregnant when he didn't pull out. I've been so over the top emotional, it's almost unbearable. My periods are textbook normal, 28 day cycles/literally no cramps or pains, medium flow, etc. Anyone experience this and it wasn't pregnancy? I've never been late 😶

(I'll be retesting again now that I'm late, but since we're in serious quarantine here, I can't go out unless my boyfriend stays home with the baby)
