Mari, the best person to ask is your doctor. We are not doctors here.
Sweet-smelling urine is normally a sign of uncontrolled diabetes, as I wrote in my first post. There may be other explanations, like ketones in the urine (from untreated diabetes), dehydration or even from eating asparagus. Maybe you have an infection and need antibiotics.
If your doctor is not concerned about this and will not do normal lab tests on you, I would find another doctor.
