UTI diagnosis

So I had my first prenatal appointment yesterday and they did a urine sample. It came back positive for a UTI. I have not one symptom of one (I’ve had plenty to know) so I decided to test myself today. It was negative.. I’m thinking maybe someone read the test late? I do not want to take an antibiotic for no reason as they give me terrible stomach issues for months at a time. I’m going to test with first morning urine in the morning, just to double check. Should I call the Dr for them to retest too?

UPDATE- went in for retest- it was negative. They said human error. So glad I thought to retest (3 times) as I have not one symptom
