Has anyone received a False positive covid test?

I’m just asking because when my daughter was 2 months she tested positive for covid. She had all the bad symptoms (wheezing , complete loss of apetite , cough, runny nose, she needed an inhaler”. I noticed she had a stuffy nose acouple days brought her to the dr , dr said she sounded great but I’ll still test her for you to ease your mind . They called back this morning and said “ She has a common cold that has to run its course and she tested positive for covid” my daughter is 4 months now so she had it 2 months ago. I’m trying to figure out so does she have a cold and covid ? I’m confused . Her symptoms aren’t nearly as bad as they were when she first had it. All she has is a runny nose . Her apetite is exactly the same .I am a firm believer of doctors so I do take doctors words but it’s just crazy to me . Ever since she tested positive the first time I became paranoid and my daughter has barely gone outside. I am bringing her to a clinic to get retested at the moment . I also am fully vaccinated. I got fully vaccinated and the week after she tested positive for covid . I’m trying not to believe these fake social media things about the vaccine, but before I was vaccinated I never knew anyone who tested positive for covid

Update

I won’t reply because I wanna remain anonymous. But when she had it the first time . She reswabbed her 14 days after and it was negative

UPDATE: as I said earlier , I was On my way to the different doctor to get tested and also to get my daughter retested . Her test was NEGATIVE
