Short-lived mild symptoms

I’m double vaxxed and in my late 20s. On Sunday and Monday I felt like I had a bad cold. Took 2 LF tests in a row Monday and both were positive so I’ve been isolating. Took another test yesterday early morning because I felt better and it was positive again.

Just sent in my PCR test today (Wednesday) so waiting to hear back and I know false positives on the LF are pretty unlikely.

Just curious if anyone else experienced only a couple days of symptoms. I feel a bit like a covid imposter!
