Hi, Thanks for posting in HCM. I understand your concern. Dark brown vaginal discharge occurs when old blood mixes in with your normal discharge. There are various causes which are associated with brown vaginal discharge. They are as follows: 1. Ovulation: Sometimes, the process of ovulation may be accompanied with little bleeding. This blood mixes in with your normal vaginal mucus, and hence, your discharge might be a little or even a dark brown. 2. Endometrial tissue: The discharge could be just an old tissue that had not passed out during the last period. This tissue may remain in the uterus for quite a while before it passes, and the discharge appears brown in colour. 3. Perimenopause: Brown discharge could be sometimes be seen just before menopause. 4. Birth control pills: Contraceptive pills can sometimes cause irregular periods and spotting with brown discharge. 5. Miscarriage: Some women might see dark brown blood or discharge during the early stages of a miscarriage. 6. Disease: Certain diseases which are associated with brown discharge include bacterial vaginosis, PID (pelvic inflammatory disease), cervical cancer and few sexually transmitted diseases. Based on the symptoms, it appears in your case to be associated with infection. The cause for it needs to be evaluated by per speculum examination and undertaking ultrasound scan of the abdomen. Kindly consult Gynecologist for complete evaluation and appropriate management. Hope the information provided would be helpful. All the best.
