Has anyone else had a similar thing? Had very mild cold symptoms on Sunday, was meeting a vulnerable relative so did a test and got a very faint positive (clear but faint). Cold symptoms were gone next day but same faint positive. Since then I’ve just had awful constant nausea and tiredness, but all have been tests negative. DD currently at uni and has been testing strongly positive for a week but with no symptoms (still positive). She wants to come home. Can I assume I have it already? Has anyone had just faint positives then all clear but still felt mildly unwell?
