I think I got it early to mid February 2020 when testing wasn't widely available. There wasn't a lot of news about COVID at the time and I caught something that wasn't the flu (tested negative) and hit me like a ton of bricks. I was having a hard time breathing, even when taking Mucinex. It wasn't bad enough to go to the hospital so I stuck it out at home. I managed the other symptoms well with Tylenol and Advil. I'm personally convinced that I caught it way earlier than most but its purely anecdotal.
