Have you noticed brown discharge in your underwear and are wondering what it means? You're certainly not alone. Brown vaginal discharge is one of the most common questions women ask themselves, and fortunately, in most cases, it's perfectly normal. However, brown discharge can sometimes be a sign that something more is going on. In this blog, we'll explain all possible causes, when you don't need to worry, and when you should see a doctor.
What exactly is brown discharge?
Brown discharge is vaginal discharge that is brown, reddish-brown, or dark brown. The color occurs because blood oxidizes — it turns brown when it is slowly discharged by the body instead of coming out quickly. It is, in fact, old blood, which sounds more alarming than it is.
Normal vaginal discharge is clear to whitish and protects the vagina by removing bacteria and dead cells. When a small amount of blood is present, the color changes towards pink, red, or brown, depending on how old the blood is.
9 causes of brown discharge
1. Beginning or end of your period
The most common cause of brown discharge is simply the beginning or end of your period. At the start of your period, the blood may not yet have fully started flowing enough to be red — it oxidizes and comes out brown. The same applies at the end of your period: the remaining blood leaves the body slowly and is already brown in color. This is completely normal and no cause for concern.
2. Brown discharge before your period (spotting)
Light brown discharge or spotting in the days before your period is also called spotting. This can occur due to a drop in progesterone levels at the end of your cycle. It is a sign that your period is approaching and is a normal phenomenon for most women.
3. Brown discharge after your period (brown loss)
Brown discharge after your period is also very common. The body cleans up the last remnants of the uterine lining, and that blood has already oxidized by then. This can last for a few days after your period ends.
4. Implantation bleeding
If you are trying to get pregnant or if you don't rule out fertilization, brown discharge around your expected period date could indicate implantation bleeding. This is when the fertilized egg implants in the uterine wall, which can cause a small amount of blood loss. Implantation bleeding is typically lighter and shorter than a normal period.
5. Ovulation
Around ovulation, some women may experience light spotting or brown discharge. This is caused by a brief drop in estrogen levels just before ovulation, which causes the uterine lining to shed slightly. This is completely normal and usually only lasts one to two days.
6. Hormonal contraception
If you start using the pill, a hormonal IUD, or another hormonal contraceptive method, or if you switch methods, your body may need some time to adjust. Breakthrough bleeding and brown discharge are very common in the first few months after starting or switching contraception. Forgetting to take a pill can also cause brown spotting.
7. Bacterial vaginosis or yeast infection
While bacterial vaginosis (BV) and yeast infections are more often associated with white or grayish discharge, in some cases they can also cause brown tints — particularly if there is slight irritation or minor damage to the vaginal wall. With BV, a fishy odor is often also present. Read more in our blog about bacterial vaginosis: causes, symptoms, and treatment.
8. Endometriosis or PCOS
With conditions such as endometriosis or polycystic ovary syndrome (PCOS), brown discharge can occur more frequently and outside the normal cycle. Endometriosis is a condition where uterine lining grows outside the uterus, which can lead to irregular bleeding and brown discharge. If you suspect you have endometriosis or PCOS, it is advisable to discuss this with your GP or gynecologist.
9. Perimenopause or menopause
Leading up to menopause, menstrual cycles become more irregular. Brown discharge, breakthrough bleeding, and changes in the amount and color of blood loss are very normal during this phase. Hormone levels fluctuate greatly, affecting vaginal discharge.
Brown discharge and abdominal pain: when is it a signal?
Brown discharge on its own is rarely a cause for major concern. But if the brown discharge is accompanied by abdominal pain, cramps, or other complaints, it is wise to be alert. The combination of brown discharge and abdominal pain can indicate:
•An ectopic pregnancy — this is a medical emergency
•A threatened miscarriage
•An infection of the uterus or fallopian tubes (PID, pelvic inflammatory disease)
•Endometriosis
If you have severe abdominal pain in combination with brown discharge, and you might be pregnant? Contact your GP immediately or go to the emergency room.
When should you see a doctor about brown discharge?
In most cases, brown discharge is harmless. However, there are situations where you should contact your GP or gynecologist:
