I can understand your concern.
High blood sugar and urinary tract infections are the most common reasons for frequent urination which are pathological.
Drinking lots of water, cold weather, staying in AC are a few physiological causes where you can feel frequent urination.
Certain medications like diuretics can also cause frequent urination but I'm sure you are not on any.
Consult a physician in person for further examination.
