Regarding COVID19 TEST RESULTS.

I have undergone covid19 test twice within span of 48hours , my first test report was COVID positive so I underwent test again same day & my second report was negative . I don't have any symptoms , I had to undergo test as my wife is having treatment with gyne and it was advised by gyne that to continue treatment we need to have COVID19 test  . My wife had to undergo COVID test twice and both time her Covid test was negative . So when my first test report came positive , I was pretty much sure it must be false positive as I didn't had any symptoms, also I underwent test just one day after my wife's test . So as soon as my first report came on 13th June , I had done testing again & this time it was negative .Now what should I consider am I Corona positive or negative .
