Can a uti make my period late. i have a negitive pregnancy test.

Usually not: Theoretically possible for UTI to cause late period but usually not an "uncomplicated"UTI. Without pregnancy causes of missed or late period can be stress,anxiety,depression,too much dieting and weight loss fast. If you miss another period go to your family doctor or you gyn doctor. Best wishes.

Not unlikely, unless: your have an infection that really makes you ill. Reasons for missed /late periods: low body weight, obesity, marked weight gain or loss, over-exercise such as in endurance athletes, breast-feeding, stress, illness, eating disorders (bulimia or anorexia), travel, hormone irregularities, drug use, medications (i.e., birth control) or med problem (polycystic ovary syndrome or Asherman’s syndrome. >
