At the very best, even the PCR tests miss ~20% of infections, and the quick tests are worse. And that very best rate depends on timing being perfect, which it rarely is. Test accuracy quickly gets worse if the test is done too early or late.
I believe that I have had Covid at least once, maybe twice, and tested negative with a PCR test the first time, and negative with the quick test the second time. That was in spite of complete vaccination, but given my age, I would likely have been hit a lot harder had I not been vaccinated. Many of my vaccinated friends have been infected, almost entirely during the latter part of this mess when Omicron cranked into gear and preventions were tapering off, but none have been seriously ill in spite of them being more or less similar in age to me. As far as I am aware, none of them has had "long Covid" either, which can be nasty even for younger peeps.
Nuff said, but negative tests cannot eliminate the possibility that you had Covid.
