You may have had it but it was gone by the time you took the PCR. I believe false negatives are far more common than false positives.
False positives are rare with the rapid antigen tests.
With Omicron and its "stealth" variant, you may need to test at peak-symptoms to get a positive at all.

“The problem with [at-home tests] is actually the other side, the false negatives, the fact that they’re not very sensitive.” Antigen tests are most accurate when you have symptoms, Dr. Baird says, since that usually correlates to having “a lot of virus” in your body—it’s easier for the tests to detect.
Even a PCR test is more accurate in the first few days after onset and may end up with false-negatives. Omicron can blow through so quickly that it may evade PCR tests if you test more than 3 days after peak symptoms.
The consensus appears to be that you should treat any positive test result as legit. Mask and isolate.

If you test positive at home, don’t assume it’s a false positive, especially if you’re experiencing the symptoms of COVID-19. “You should stay home or isolate for 10 days and wear a mask if others could have contact with you,” the CDC recommends. “Also, tell a healthcare provider about your positive test result and stay in contact with them. If your illness becomes severe, seek medical attention.”
