I had unprotected oral (give/receive) and protected anal (receive) with no semen involved with a trans (i m a male). I had an antibody test at 5 month (144 days) and it was negative. I retested 2 weeks later with elisa after a covid infection(still waiting for the result).
Since you had no risk everyone but you knew it had to be negative. If you continue to worry, see a therapist, because disease can't occur when there is no possibility of infection.
