12th day of Covid! What's next?

I'm on my 12th day with this damn COVID... I was very sick the first 6 days (fatigue, muscle pain, fever, nausea, short breath, diarrhea). I went back to work last Monday, but I had a hard time being productive all week. I don't think I have the "brain fog" symptom, but I get exhausted quickly, I have hot rises and get sweaty as soon as I move and a persistent cough... On the other hand, I think my sense of smell is slowly returning. Are these normal symptoms? I know it varies from person to person, but after how long does the fatigue and the cough normaly go away? Thanks!
