UTI & Pregnancy Test ?

Hi ladies. Sooo, I've completely missed my period, and I was planned on testing today, but yesterday I woke up with a pretty bad UTI. I haven't been able to make it to my doctor yet, so I've been taking Azo to help keep it at bay until I can see her for some antibiotics. I'm wondering if Azo will obscure the results for the pregnancy test, like give a false negative from diluting my urine..? Google seems to have some conflicting answers, so I thought I'd ask here for personal experiences. Thanks to anyone who can help!
