Sounds like you had it a bit worse than i did. Yes, almost everyone in my wife village has had it and almost all of her friends. As for the ATK, we tested as a strong positive straight away, the test line coming up before the lateral flow even making to the control line but, I also swab our throat and nose. Not just the nose, I've been told that the ATK test doesnt pick up omicron as easily unless there is a heavy viral load if you only swab the nose.
