UTI infection and Late Ovulation

Hello!
     This has become quite frustrating for me. I have been doing the ovulation tests for 5 days now this month and no LH Surge has been detected. This is throwing my fertile window over in the app by adding a days to it and moving it over. This is the third month I've been doing ovulation tests and this is the first month that my LH Surge is late. I am in the middle of a UTI infection and I'm wondering if that can throw ovulation off or throw off test results. Anyone have any answers?
