Brown Spotting After Period: Normal vs. Concerning Patterns

Light brown spotting for 1–3 days after menses is typically normal. It represents oxidized, older blood and endometrial debris clearing from the vaginal vault.

When to Investigate

Consult a clinician if spotting:

• Persists >7 days post-period
• Is heavy (soaking protection)
• Occurs frequently between cycles (intermenstrual bleeding)
• Is accompanied by pain, dyspareunia, abnormal discharge, or fever
• Occurs after menopause (any bleeding is abnormal)
• Follows new hormonal contraception (evaluate at 3-month mark if persistent)

Potential Pathologic Causes

• Endometrial polyp or submucosal fibroid
• Cervical ectropion/polyp
• Atrophic vaginitis (low estrogen)
• Endometritis (post-procedure, retained products)
• Coagulopathy or anticoagulant use
• Cervical/endometrial neoplasia (rare but must exclude)

Evaluation: history, speculum exam, cervical screening (if due), pelvic ultrasound, endometrial biopsy if indicated.
