Light Pink Discharge After Intercourse: Causes & What to Expect

Postcoital pink spotting is common and often benign, but warrants evaluation if persistent or accompanied by other symptoms.

Common Benign Causes

• Cervical Ectropion/Erosion: Columnar epithelium on ectocervix bleeds easily with contact.
• Atrophic Vaginitis: Low estrogen → fragile mucosa (perimenopause, postpartum, OCPs).
• Ovulation Spotting: Mid-cycle estrogen dip → slight endometrial shedding.
• Implantation Bleeding: 6–12 DPO; light, brief; possible early pregnancy sign.

Concerning Causes

• STIs: Chlamydia, gonorrhea, trichomoniasis → cervicitis.
• Cervical Polyps: Fragile vascular stalks.
• Cervical Dysplasia/Cancer: Friable tissue; screening (Pap/HPV) essential.
• Endometriosis/Adenomyosis: Associated with dyspareunia.
• Uterine Fibroids/Polyps: Submucosal lesions.

Action

If spotting is isolated and resolves, monitor. If recurrent, heavy, painful, malodorous, or with abnormal bleeding pattern—see a clinician for speculum exam, STI testing, and Pap/HPV per guidelines.
