It doesn't sound like you have a UTI.

If you did, a urine test would be positive, you would be wanting to go all the time and when you got there, you would only pass a little and the urine would sting as you passed it, or as the flow stops.

A vaginal yeast infection would show itself with a white discharge so in the absence of all the symptoms of a UTI or yeast infection, I'd be most likely to agree with your mom and continue to drink lots of water.

An irritation around the opening to the bladder might cause your symptoms. This could be caused by sexual intercourse, sexually transmitted diseases, tight clothing or wearing of pads.

If your symptoms persist for a week, or you develop a fever, I suggest you make an appointment to see your doctor.
