Hard to say: There can definitely be false positive (or false negative!) antigen tests for COVID, so yours could have been false positive. It also seems to be the case that antibodies may not last more than a few months (although more recent studies indicate immunity may last longer despite negative antibody tests) - so unfortunately there is still a lot of uncertainty.
