Hello,
there is not enough information to establish the diagnosis of diabetes mellitus. Diagnosing diabetes requires fasting lab blood sugar test 126mg/dL or higher or a random blood sugar test equal to or above 200mg/dL with symptoms of hyperglycemia or blood sugar equal to or higher than 200mg/dL 2 hours after ingestion of 75 grams of glucose (oral glucose tolerance test). Glycosylated Hemoglobin testing for diagnosis is controversial. Since you had no sugar in urine it's rather unlikely that you had some sustained blood sugar elevation, although you could have diabetes with mild fasting glucose elevations and no glucose int the urine. An oral glucose tolerance test would give you a definite answer about diabetes.
I hope I've helped!
