What Is a Missed Period?

A missed period means your menstrual period does not arrive when expected. One missed period may happen from temporary factors such as stress, travel, illness, sleep changes, weight change, exercise, or medication.

However, repeated missed periods, no period for several months, missed periods with pelvic pain, or missed periods with possible pregnancy should be checked by a gynecologist.

Common Causes of a Missed Period

1. Pregnancy

Pregnancy is one of the most common causes of a missed period. A urine or blood pregnancy test may be recommended if there is any possibility of pregnancy.

2. Stress

High stress can affect hormone signaling and delay ovulation, which may lead to a late or missed period.

3. PCOS

Polycystic ovary syndrome, or PCOS, can cause missed periods, irregular cycles, acne, excess hair growth, weight changes, and fertility concerns.

4. Thyroid Problems

Both overactive and underactive thyroid conditions may affect menstrual cycles and cause missed, irregular, heavy, or light periods.

5. Weight Changes

Rapid weight loss, weight gain, low body weight, dieting, or eating disorders can affect ovulation and menstrual regularity.

6. Intense Exercise

High-intensity training, endurance exercise, or low energy intake may contribute to missed periods.

7. Birth Control

Starting, stopping, or changing birth control pills, hormonal IUDs, injections, implants, or emergency contraception can change bleeding patterns.

8. High Prolactin

High prolactin may cause missed periods, irregular periods, breast discharge, or fertility problems.

9. Perimenopause

Patients in their 40s or sometimes late 30s may experience missed or irregular periods due to perimenopause.

10. Breastfeeding

Breastfeeding may delay the return of periods due to hormone changes.
