Covid or common cold?

I haven’t been feeling well since sunday. all Mild symptoms like headache, tired, sore throat and runny nose. No fever and perfectly functional, just underlying discomfort, so I am conflicted on if I need a test or not. I don’t want to take time/resources for people who need it most, or expose myself unnecessarily either. I’m 26, no health conditions. and my husband is feeling totally fine all week.
