What does ketone +2 mean? i was never diagnose with diabetes or pre diabetes. i feel fine. also currently 6 weeks pregnant?

Ketones are found in the urine when your body begins to convert fat as an energy source to the sugar needed to sustain a normal level. It suggests a period of dieting or not ingesting enough carbohydrates to keep the blood sugar level up. By itself it is not an indicator of something bad.

If you have been nauseous and vomiting that could explain the ketone bodies as you may not be getting enough carbohydrates and mobilizing fat for energy.
