Hi,
The possible causes of your brown or red discharge are:
- While being on birth control pills some amount of menstrual irregularities like inter menstrual spotting can be expected and sometimes that mixed with vaginal mucous can present as brownish discharge.
-Local causes like cervical erosion, polyps etc can also lead to red or brownish.
If the discharge is persisting, better to consult your Gynecologist once, go for clinical examination and if needed
ultrasound, with this workup the possible cause of your problem can be identified and treatment can be planned accordingly.
In case of local causes like erosion, course of local antibiotics can help to decrease the problem. No need to worry as according to your history and age there may not be any major problem.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Sree Gouri S. R., OBGYN
