“Urinating (peeing) very little even though you feel like your bladder is full” is a common complaint from girls/women who have symptoms of a urinary tract infection (UTI). Your symptom(s) may be caused by a UTI or from something else.
UTIs are more common among girls and adult women who have had a UTI before, and for girls who are sexually active. Since females have a shorter urethra (than males), it is easier for bacteria to enter the urinary tract and cause symptoms. Call your health care provider to get checked to see if you have a bladder infection or something else. There is treatment!
