Brown discharge before a period is entirely normal and almost never a cause for concern. It is rare any type of period blood color or texture changes are. Brown discharge in particular is a just result of older blood mixing with cervical mucus, but to ease your mind, let’s look at the most common causes of brown discharge before a period.
Causes of brown discharge before a period:
Ovulation: Sometimes ovulation will cause slight spotting which takes time to reach the vaginal opening resulting in it appearing brown by time it exits. Ovulation is normal in those who have hit puberty and occurs on average mid-cycle. Not all women experience ovulation spotting.
Hormonal imbalance: Hormonal imbalance such as low progesterone can cause spotting periodically throughout your cycle. Any cause of spotting or very light bleeding can result in brown discharge before a period. Birth control or herbal options such as vitex may help balance horomones.
Implantation bleeding: When a fertilized egg implants into the uterine wall sometimes a small amount of bleeding occurs which can present as brown discharge before a period. If you’ve had unprotected sex and pregnancy is possible, you can read more about telling implantation bleeding from spotting here.
Cervical or vaginal damage: Damage to the cervix or vaginal wall may also cause light bleeding. Sex or PAP smears can cause this sort of damage.
Infection: Certain infections including yeast infections, bacterial vaginsosis and sexually transmitted diseases can cause inflammation to the cervix which also causes bleeding. In this case, it is likely you would see other symptoms as well such as odor, itching, or rash. Continuous brown discharge should be mentioned to a doctor.
Beginning or end of your menstrual cycle: Finally, brown discharge just before or after your period is just a result of light bleeding beginning or ending.
