Vaginal Discharge & Spotting: Decoding Colors and Timing

Brownish discharge or spotting around your expected period is often normal, but persistent or atypical patterns deserve evaluation.

Common Benign Causes

• Premenstrual spotting: Progesterone drop before menses; brown = old blood.
• Ovulation spotting: Mid-cycle, pink/brown, 1–2 days.
• Hormonal contraception: Breakthrough bleeding on pills, IUDs, implants.
• Perimenopause: Erratic cycles, spotting.

Potentially Concerning Causes

• Pregnancy: Implantation bleed (6–12 DPO), subchorionic hematoma, ectopic (emergency).
• Infection: Cervicitis (chlamydia, gonorrhea), BV, yeast – often with odor, itching, dysuria.
• Structural: Polyps, fibroids, cervical ectropion.
• Endometriosis/adenomyosis: Cyclic pain + spotting.
• Malignancy: Rare but possible (cervical, endometrial) – postmenopausal bleeding always warrants workup.

When to See a Clinician

• Spotting >7 days or recurrent >3 cycles
• Postcoital bleeding
• Postmenopausal bleeding
• Associated pain, fever, foul odor
• Positive pregnancy test with bleeding

Workup may include speculum exam, STI testing, pelvic ultrasound, endometrial biopsy (if >45 or risk factors).
