UTI question

i went to the doctor today because i’ve been having some back pain. she tested my urine and said that i have a small amount of leukocytes but it most likely isn’t an infection. lately whenever i go pee i feel like i have to pee immediately after and my back has been non stop killing me. do you think she’ll call back saying it’s a UTI? i’m hoping so that i can get some relief!

also side note: i was nervous that i was pregnant due to these symptoms but i got my period today and i’m on birth control so can someone confirm that that’s definitely not the case?
