I had 2 days of mild symptoms and negative lateral flow tests. Then a positive test with head cold symptoms, painful sinuses, fatigue. No cough, just a ticklish throat. No fever. No loss of taste/smell. Now I am 12 days after that first positive test and still getting a strong positive. My symptoms have subsided, leaving me with a small amount of residual mucus in my nose and a minor post nasal drip. When did you finally test negative, or did anyone stop testing after the full 10 days?
