I'm On Probation, I Had To Take An Etg Test,

I'm on probation, I had to take an etg test, I had not even a half cup of coffee and about 8 ounces of orange juice almost two hours before testing. My urine came out lighter than it usually does. I had nothing else to drink since the evening before. I don't drink or do any drugs, should I be worried of a dilute result?
