Generally, most women who have a urinary tract infection do not experience missed or delayed periods. The most common reasons that affect the period include stress, anxiety, and depression, explains the N.Y. Times.
The urinary tract system includes two kidneys, two ureters, a bladder, and a urethra. Urinary tract infections usually occur when bacteria from the digestive tract enter the urinary tract, through the urethra, and begin to multiply in the bladder, explains the Mayo Clinic. A majority of urinary tract infections are caused by a type of bacteria called Escherichia coli, or E. coli. Women tend to get urinary tract infections more often than men because the urethra is shorter in women than in men, so bacteria has a shorter distance to travel.
