Confused... Help!!

I’ve been ttc for over two years! I finally seen a positive test last night. And decided to test with fmp to see if the line would be any darker. This morning it was fainter/about the same as it was last night. I do currently have a uti. Would that show up as a positive test result? According to google, it happens. 😭 now I’m heartbroken that this test may have been a false alarm..
