Leukocyte in urine but no bacteria

So my primary doctor did a complete blood test and urinalysis (I've been dealing with heart palpitations) and everything came back normal except for my urine as it seems I have leukocyte in my urine but yet no bacteria is present?

I have no symptoms of a uti and haven't for a while. Last time I had what I thought was a uti was because I was having pelvic pain and I bought a urine test that came back positive so went to the doctor they did a urine test strip and said I had a uti (this was back in July '22) and prescribed me antibiotics and so when they were done I did another urine test strip again bc I was still having pelvic pain and it was still positive so went back and they prescribed me antibiotics again bc their test also came back positive and after that I never did another at home test bc I figured if I had a uti it would certainly be gone but I did go to my gynecologist for the pelvic pain back in August of 22 and they did an ultrasound but I never heard back so I assumed it was good as now again I have leukocyte in my urine but no bacteria. I'm starting to get a bit worried bc I deal with bloat often (but I also have ibs) and my pelvis hurt sometimes still and I know some cancers (such as bladder and ovarian) can cause leukocyte to show up in your urine as well as bloating and pelvic pain.. Has anyone had this happen and it be all good. I have another appointment with my doctor in a couple weeks and will bring up the bloating and pelvic pain. I'm not sure what to think at this point 😔
