Sorry im confused. You think you have covid but cant test positive on a test?
Im long covid person and you can only test positive the first week or maybe 2nd week. But the pvf can last months. Many, even those without pem on the covid boatds, still have symtpkms. Mine only lasted 4 months but then i got crippling pem later after.
Sorry not sure if this is what uou are asking. But there is no way you would test positive from feb. someone who did would be an extreme outlier, indont think we even have that on record. Did he scan your lungs for covid damage? I believe mri is the the standard, ct doesnt always work.
Oh, antibodies? I never had them and no many who never had them. Many many people.
Esp from feb id be very suprised even if you didnhave them that youd still have them now.
