Understanding Frequent Periods: What to Do When You Have Four Periods in Two Months

Four menstrual periods in two months (cycle ≤14 days) is abnormal (polymenorrhea) and requires medical evaluation. Normal cycles are 21–35 days.

Potential Causes

• Anovulatory Bleeding: No ovulation → no progesterone → unstable endometrium sheds irregularly. Common in PCOS, perimenopause, stress, weight extremes, thyroid disease.
• Structural: Endometrial polyps, submucosal fibroids, adenomyosis.
• Hormonal Contraception: Breakthrough bleeding on OCPs (especially missed pills, low-dose), IUD (copper: heavier; hormonal: spotting initially), implant, depot.
• Coagulopathy: von Willebrand disease, platelet disorders.
• Medications: Anticoagulants, antipsychotics, corticosteroids.
• Pregnancy-Related: Implantation bleeding, subchorionic hematoma, miscarriage, ectopic (always rule out).
• Infection: Cervicitis (chlamydia, gonorrhea), endometritis.

Immediate Steps

1. **Pregnancy Test** (urine hCG) – rule out pregnancy complications.
2. **Track Bleeding:** Dates, heaviness (pads/tampons), associated symptoms.
3. **See Clinician** for: history, pelvic exam, CBC (anemia), TSH, prolactin, pelvic ultrasound, STI testing.
4. **Endometrial Biopsy** if >45 or risk factors for hyperplasia/cancer.

Treatment Depends on Cause

• Hormonal regulation (OCPs, progesterone IUD, cyclic progesterone).
• Treat underlying (thyroid, PCOS, coagulopathy).
• Remove structural lesions (hysteroscopic polypectomy/myomectomy).
• Iron supplementation if anemic.

Do not ignore frequent bleeding. It can lead to iron-deficiency anemia and may signal treatable pathology.
