Frequent urination? What are my options?

I have been dealing with frequent urination since 2018. Past 2 years it hd reduced and became normal, but again since 6-7 months i am having that again and losing weight as well. Everytime i go to pee, there's normal amount of urine that i do, not less. Checked for uti, urine culture normal, usg abdomen normal, left kidney ectopic and malrotated. Kft fine, just creatinine was 1.24, maybe due to dehydration and eating nonveg. Uroflowmetry normal flow. What other tests can help me? I am frustrated with this now, this is not anxiety as well. I am scared if something is wrong with my spine? Help me out here please, if something else could help me? I need a comprehensive checkup and I would only give up and choose to live with that if nothing comes up with the tests. Please help me, what are my options?
