The Mayo Clinic does not list a delayed period as a symptom of a urinary tract infection. Likewise, WebMD does not list a urinary tract infection as a cause of a delayed or missed period.
WebMD states that a change in physical or emotional stress can cause a missed or delayed period, so if a woman's body is under stress, it would not be uncommon for a period to be delayed. However, typically speaking, a delayed period is not a common symptom of a urinary tract infection.
Common symptoms of a urinary tract infection listed by the Mayo Clinic include: a strong, persistent urge to urinate; a burning sensation when urinating; urine that appears cloudy; passing frequent, small amounts of urine; strong-smelling urine; pelvic pain in women, and rectal pain in men.
