Brown Period Blood: What Causes It, and When To See a Doctor?

Do you ever look at your period blood and wonder why it’s brown instead of the usual red?

Brown period blood is pretty typical during menstruation, but still can give rise to confusion and worry for many women.

Even though not all cases of brown period blood calls for alarm, it’s important to be aware of what could cause this color change in menstrual flow as well as other signs that may suggest there are some underlying issues.

Period blood colors

Period blood color can range anywhere from bright red to dark brown.

Blood color can tell you your state of reproductive health, whether you’re healthy or you got an infection or hormonal imbalance.

But most of the time, the color just tells you how long the period blood has been in the uterus.

Is brown period blood normal?

The period blood consistency and period blood color can change during the menstrual cycle, and that is totally normal and expected.

If your period blood is thin and watery one day and thick and clumpy the day after that, you have no cause for concern, it is all a part of the process.

Menstrual blood can range in color from bright or dark red to bright or dark brown, with individual experiences varying, resulting in some having a heavy period while others have light period.

Periods tend to vary in length, heaviness, and level of discomfort amongst women, and that is to be expected.

Causes for brown period blood color

There can be different reasons why it happens, but generally, it’s nothing to stress over.

Most of the time this dark-colored discharge is just old blood or already dried-out blood that has had enough time to change its color before being expelled from the body.

Certain health medications like birth control pills and hormone injections may cause darker menstruation periods too.

In rare cases, you should seek help from a healthcare provider because there might be an underlying medical issue at hand that needs attention for you to stay healthy!

1. End of your period

Normal menstrual period blood is red, but it can appear brown as your cycle is getting at the end of your period.

The blood tends to be red at the beginning of the cycle because the body is just starting to shed the uterine lining.

The discharged menstrual blood is old blood and tends to be discolored by the last few days of the cycle starting from bright red blood to dark red blood and finally to brown.

2. Birth control or menopause

Brown spotting or brown discharge can also happen sometimes in the middle of the cycle while you are ovulating.

This often happens with women who are just starting new hormonal birth control, younger girls who are just starting to have their periods and experience their first period, or women that are close to menopause.

If you happen to experience bleeding between periods often, make sure to visit your doctor just to make sure that it is not a symptom of more serious medical conditions.

3. Early pregnancy and implantation bleeding

During pregnancy, some women might experience implantation bleeding, which can also result in brown spotting.

This occurs when a fertilized egg attaches itself to the uterine lining, causing slight bleeding.

The blood takes time to travel through the cervix, and by the time it reaches the vaginal opening, it may appear brown due to its exposure to air and the passage of time.

4. Miscarriage or an ectopic pregnancy

Heavy brown vaginal discharge or bleeding during pregnancy can also indicate more serious matters, such as miscarriage or an ectopic pregnancy (an occurrence in which the fertilized egg implants in a fallopian tube instead of the uterus).

If you happen to experience any heavy vaginal bleeding during pregnancy, brown or not, make sure to speak to your doctor or obstetrician as soon as possible.

5. Hormonal fluctuations

Fluctuations in hormone levels, such as those experienced during perimenopause or as a result of certain medications, can impact the color of menstrual blood.

Brown blood can be an outcome of these hormonal changes, as they can affect the rate at which the uterine lining is shed.

This can lead to older blood being expelled, resulting in a brownish hue.

6. PCOS – polycystic ovarian syndrome

Heavy brown bleeding between your periods can be a sign of an underlying medical condition, most likely polycystic ovarian syndrome (often referred to as PCOS).

Polycystic ovarian syndrome occurs when your body produces too much testosterone, making your ovaries larger and developing abnormal growths.

PCOS can also cause issues with fertility, as it messes with ovulation.

10 most common symptoms of PCOS:

• Late or irregular periods
• Increased hairiness
• Ovaries that have cysts
• Weight gain
• Acne & oily skin
• Infertility
• Darkening of the skin
• Fatigue
• Heavy Periods
• Hair loss

When to see a doctor?

As we have previously mentioned, brown blood caused by period is often not a cause for concern.

However, when this occurrence is accompanied by other symptoms, you should definitely seek immediate medical attention as it could be sign of bacterial infection, sexually transmitted infection, endometriosis, pregnancy or some other condition.

Some of the symptoms include:

• Heavy vaginal bleeding between periods
• Long period – longer than seven days
• Having no period for longer than three months
• Vaginal bleeding between periods
• Vaginal itching
• Fever above 38º C
• Dizziness and vertigo
• Pale skin, below the nails or in general

If you suspect or know that you are pregnant, and you notice dark bleeding, especially with blood clots, make sure to visit your doctor immediately.

This occurrence may signify a miscarriage, and curettage may be necessary to clean the uterus.

Conclusion

Brown period blood is generally considered as normal but it’s crucial to pay attention to any unusual changes or persistent symptoms.

Understanding the factors that can influence the color of your menstrual blood, such as the end of your period, hormonal shifts, and even pregnancy, empowers you to navigate your reproductive health with confidence.

While occasional brown period blood is often benign, seeking medical advice when accompanied by concerning symptoms ensures that your well-being remains a priority.

The brown color and foul odor of your period likely happen because you are on the last few days of your period when the discharged period blood tends to be older.
