If I contract covid, how long will I feel ok before it hits me?

Do I have to get my affairs in order in a week’s time? Because I could be helpless in two?

I don’t need to be reminded that not everybody gets sick and that some who do won’t have a bad case. I have to consider worst-case scenario.

I’m completely tied up with the aftermath of my husband’s death (not from covid) two days ago. The hospital gave us plenty of opportunities for exposure, my sons and I, beginning Thursday night,1/14. Assuming I get it—how long do I have before I can’t function normally?

I really want to know. I can’t leave a mess behind if I can help it, but the time window seems awfully short.
