Period Delay

Understand period delay, and its causes and related symptoms.

Period Delay


Period delay is when a woman’s menstrual period does not occur at the expected or usual time, resulting in a missed or late period.


Occasional period irregularities can be normal but persistent or unexplained delays can be caused by various factors, including:

  • Pregnancy is the most common reason for a missed period
  • Breastfeeding
  • Physical or emotional stress
  • Significant weight gain or weight loss
  • Polycystic Ovary Syndrome (PCOS)
  • Hypothyroidism or hyperthyroidism
  • Intense or excessive physical activity or exercise
  • Medications and contraceptives
  • Perimenopause
  • Diabetes


Depending on the underlying cause of the delayed period women might experience these symptoms in addition to period irregularity:

  • Abdominal cramping
  • Breast tenderness
  • Mood changes
  • Fatigue and low energy levels
  • Changes in vaginal discharge
  • Hot flashes (typical in perimenopause)
  • Excessive hair growth and acne (typical with PCOS)
