You have very mild non progressing albuminuria & proteinuria with otherwise normal kidney function, but you don't mention whether a microscopic examination of your urine sediment shows microhematuria which could be due to a mild degree of chronic glomerulonephritis or other glomerular pathology which could explain the proteinuria. A nephrologist can advise you best.
