The 10 Most Common Causes of a Delayed Period
1. Early Pregnancy: The most common physiological cause of missed menses in sexually active individuals of reproductive age.
2. Emotional or Physical Stress: High cortisol and CRH levels suppress hypothalamic GnRH secretion, delaying LH surges and ovulation.
3. Polycystic Ovary Syndrome (PCOS): Elevated anovulatory androgen levels lead to irregular, delayed, or missed cycles.
4. Thyroid Dysfunction: Both Hypothyroidism (underactive) and Hyperthyroidism (overactive) alter TSH and prolactin, impairing cycle regularity.
5. Stopping Hormonal Contraception: HPO axis reactivation after birth control pills or Depo-Provera injection can take 1 to 6+ months.
6. Low Energy Availability & RED-S: Restrictive dieting, sudden weight loss, or intense athletic training can trigger Functional Hypothalamic Amenorrhea (FHA).
7. Perimenopause Transition: Individuals in their 40s may experience variable cycle lengths as ovarian follicular pools decline.
8. Recent Illness or Infection: Systemic physiological stress temporarily delays follicular maturation.
9. Certain Medications: Antipsychotics, antidepressants, thyroid meds, or chemotherapy can affect prolactin and cycle timing.
10. Normal Cycle Variation: Menstrual cycles naturally vary by a few days from month to month without underlying pathology.
11. Postpartum & Lactation: For individuals who have recently given birth, understanding when periods return after having a baby depends on breastfeeding frequency, lochia recovery, and prolactin levels.
When to Take a Home Pregnancy Test
If you are sexually active, take a home urine pregnancy test 1 day after your expected menses or 14 days following potential exposure. Modern hCG blood and urine tests provide definitive early confirmation.
Clinical Triage: When to Consult a Healthcare Provider
Consult a primary care clinician or gynecologist if you miss 3 consecutive periods (secondary amenorrhea), experience severe pelvic pain, or notice sudden hirsutism (excess facial/body hair) or severe acne.
डॉक्टर से कब परामर्श लें (When to See a Doctor)
- •Skipping periods for 3 consecutive months when not pregnant.
- •Sudden unexpected hair growth on face or body paired with missed cycles.
- •Severe pelvic pain, unusual vaginal discharge, or fever.
