13 dpo with intense uti pain.

woke up this mornin to pee abd was fine woke up 2 hrs later and had the worst pain ever. got a bfn at 12 dpo and now that I'm on the pain relief than turn your pee orange I doubt I'll get an accurate result. don't think uti is a prego symptom I am very prone to them. I'm just scared it will ruin my chances of getting a bfp until it's taken care of. af us due tomorow but hopefully she doesn't come
