Prediabetes usually is asymptomatic, but sometimes you may get fatigue, thirst, and frequent urination.

For this answer I would refer you to the web site of the American Diabetes Association= ADA.edu They have brochures that explain this & tables with values. Unfortunetly most prediabetes is asymptomatic & hard to detect. A fasting BS between 100 & 125 and/or a HbA1c test between 5.8-6.5 are usually considered pre diabetes.

There are usually no symptoms associated with prediabetes.

Worrying symptoms could be excessive thirst and urination with increased appetite and weight loss. These symptoms indicate a high sugar state. If you have pre-diabetes l, lifestyle management (low carb diet and exercise is the first line treatment), if not improving then adding metformin or other DM medications would be the next step.
