Brownish Discharge After Period: Causes & When to See a Doctor

Brown discharge at the end of a period is usually normal. It represents old blood that has taken longer to exit the uterus, oxidizing and turning brown. It typically resolves within 1–2 days.

When to See a Doctor

Consult a healthcare provider if the discharge:

• Is heavy or prolonged (>3 days)
• Has a foul odor
• Is accompanied by pelvic pain, cramping, or fever
• Occurs between periods (intermenstrual bleeding)
• Is associated with pain during sex
• You are postmenopausal

Possible underlying causes include hormonal imbalance, infection (bacterial vaginosis, STIs), cervical polyps, endometriosis, or, rarely, cervical/uterine cancer.
