UTI and Wondering when to test

I went to the doctors on 5/10 because I was having UTI Symptoms, while the doctor agree that I did in fact have a UTI however I was supposed to get my period on 5/8 and still no period. My period tend to be irregular most of the times but me and my husband are TTC and I just need advice on why should I test? Ps I don't have any symptoms 😥 Any insight would be amazing
