What if I get called in for work tomorrow while I wait for the Covid 19 test results? What do I say?

I don’t wanna risk anyone getting harmed because I might have it. I don’t want to be selfish and I’m not a selfish person.

I am feeling a lot better than the last couple of days. I did tell my boss that I took the test on Friday and I get my Covid 19 test results from 2-5 days but on the paper I was told I would have to self quarantine until I get the results. I did that for three days. If I feel better tomorrow, should I go to work while I wait for my results. My dad said I should stay home but call my boss tomorrow morning but take care of myself be I would be putting everyone at risk. I work at a pet store.
