What Could Be Causing My Urine To Have A Strange Odor For 2 Months Despite Drinking More Water And Eating Healthier?

Hi! My urine has been having a strange odor for the last 2 months. Haven t been able to get to a doctor from lack of insurance, but its been ranging from ammonia, to sulfur, to pretzels??? I ve been drinking TONS more water and eating healthier and just nothing seems to help. My urine is still yellow, but I m not seeing any blood. I AM uncomfortable sometimes during urination though. I hope this is enough information
