That sucks. I had it back around Thanksgiving. I picked it up on a Saturday at a family gathering. I started getting the first symptoms (nasal congestion for me) about 4 or 5 days later. I was tested on day 7. I tested negative but my wife tested positive at the same time (as did everyone else at the gathering). The doctor giving us the results said I was almost certainly a false negative and that I had it. I started getting actually sick the next day.
I ran a low grade fever, had bad fatigue, chills, a cough, loss of sense of smell, and, worst of all, shortness of breath. That lasted about a week. At the end of a week I developed nausea and intestinal symptoms that lasted a couple of days. After that it was very much an up and down situation for another week. One day I'd be okay and the next I'd have shortness of breath and bad fatigue again.
About 3 weeks from when I was exposed and after two weeks of being sick I turned the corner. The shortness of breath went away and the cough improved. I had a couple more weeks of fatigue but it steadily improved. I still get winded easily though. That will probably persist for a while.
Of the family that contracted it, we all experienced symptoms differently. My brother in law's family (the ones that brought it to the gathering), had mild symptoms that lasted a few days. It was like a mild flu. My father in law experienced severe nausea that lasted a couple weeks but few other symptoms. My wife had most of what I had except no breathing issues.
Some other things to watch out for. First, sleep issues. Covid caused some pretty bad sleep disruptions for my wife and I. Next, anxiety. The breathing issues triggered bad anxiety for me which in turn caused the breathing issues to get worse. Also, my wife and I both had a brain fog that made concentrating very difficult.
My best advice, don't overdo it when you start to feel better. It will just make you feel worse when the roller coaster of symptoms dips again.
