What’s wrong with brown discharge? Brown vaginal discharge is caused by a small amount of bleeding from the vagina. It is normal to have brown vaginal discharge when the menstrual period comes and goes and the volume decreases on the 6th to 7th day. When there is still brown discharge after 7 days of menstruation or when you should not have menstruation at all, there may be gynecological diseases, such as a small amount of vaginal bleeding or cervical polyps caused by endocrine disorders. In short, as long as the brown discharge does not occur when your period is about to be cleared and you have brown vaginal discharge when you are not supposed to have your period, it is recommended that you go to the hospital for a checkup and depending on the results of the checkup, how to treat it.
