Uti?? Does it look like it

I bought a home test the top testes for leukocytes and bottom for Nitrite. As you can see the top is positive but the bottom is negative .. but im unsure if i have a uti bcs one is positive and other negative. I’ve been to the Dr 3x bcs i keep having uti symptoms bcs my urethra burns after i pee in the morning and alot of pain and pressure/fullness on lower stomach like if i need to pee constantly,but that can also be bcs im 28 weeks. The first time i got antibiotics . The second time dr said i only tested positive for blood in urine so she gave me antibiotics just incase. The third time they told me that i did had some bacteria but it was normal to have some bacteria so they didn’t gave me nothing. Ugh I really don’t know what to do anymore 😕
