Looked this up on Google but there doesn't seem to be a definite answer. I was exposed to Covid last Friday.

How many days do I need to isolate? I am not sick at all other than my usual asthma symptoms. My friend became quite ill with flu like symptoms the day after I saw him.

He went to the doctor and had a monoclonal antibody test, but they didn't tell him which variant he has...just that he has Covid.

Online concensus appears to be that I could still become sick 14 days later if he has Covid 19. If he has the Delta variant, I would get sick 5.61 days after exposure...so I've already passed that mark.
