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.
I learned more about the PCR test over the weekend, it is so sensitive that it can still report positive results in recovered COVID patients for up to 90 days after the start if the infection, this is why they tell patients to not get PCR tests until 90 days after they recover. So if I had it on Friday, the PCR test should still be detecting it.
When to Get Tested
Review the scenarios below to determine when to get tested. If you have had COVID-19 in the past 90 days and recovered, you do not need to be tested unless you develop new symptoms. If you do have new symptoms, consult a healthcare provider for testing recommendations.

People who have recovered from COVID-19 can continue to test positive for up to 3 months after their infection. CDC does not recommend retesting within 3 months after a person with COVID-19 first developed symptoms of COVID-19 (or the date their sample was taken for their first positive viral diagnostic test if their infection was asymptomatic).
