What Color Should Your Period Blood Be?

By Femometer | Tuesday, June 11, 2024

The color of menstrual blood changes throughout the cycle, providing valuable information about your reproductive health. Therefore, it's essential to understand the normal changes in period blood during menstruation. Additionally, keeping a record of your menstrual blood color can help detect abnormal health conditions early.

Types of Period Blood Colors


Bright Red Blood

Bright red blood is typically seen at the start of your period, indicating that the blood is fresh and flowing quickly from the uterus. This is a sign that the uterine lining is shedding and your menstrual cycle is functioning normally. Consistent bright red blood throughout the period can suggest a steady and healthy flow.


Dark Red or Brown Blood

period blood color

Dark red or brown blood is common towards the end of your period. This color change occurs because the blood has taken longer to leave the uterus, allowing it to oxidize. Brown blood might also appear at the beginning of your period as your body expels older blood from the previous cycle. Generally, this is not a cause for concern and is a normal part of the menstrual process.


Black Blood

Black blood, often seen at the very end of a period, is older blood that has had more time to oxidize before exiting the body. While the sight of black blood can be alarming, it is generally normal and simply a result of the blood aging as it leaves the uterus.


Orange Blood

Orange blood can sometimes be observed when menstrual blood mixes with cervical fluid, giving it a lighter, orange hue. However, orange blood can also be a sign of infection, especially if accompanied by a foul odor or discomfort. If you notice orange blood and other unusual symptoms, it’s important to consult a healthcare professional.


Pink Blood

Pink blood is usually a mixture of menstrual blood and cervical fluid, appearing lighter in color. This can occur at the beginning or end of your period. While generally normal, pink blood outside of your menstrual cycle can be a sign of hormonal changes, pregnancy, or other health issues.


Green Blood

Green blood is not typical and can be a sign of an infection, such as bacterial vaginosis. If you notice green blood, it’s crucial to seek medical advice promptly to address any potential underlying infections or health concerns.


Jelly-like Clots

Experiencing jelly-like blood clots during your period is relatively common. These clots are made up of blood and uterine tissue and are usually harmless. However, if you notice large clots (bigger than a quarter) or an increase in the frequency of clots, it might indicate a heavier flow or other underlying conditions, such as fibroids or hormonal imbalances. In such cases, consulting with a healthcare provider is advisable.

When to Seek Medical Advice

While variations in menstrual blood color are typically normal, significant changes or unusual symptoms can indicate underlying health issues. If you experience:

persistent orange or green blood, large or frequent blood clots, unusual odors, severe pain or discomfort. It’s essential to consult a healthcare professional. These symptoms could signal infections, hormonal imbalances, or other reproductive health concerns that may require treatment.

Understanding the color of your period blood can provide insights into your menstrual health and help you detect potential issues early. Always monitor your cycle and seek medical advice if you notice significant changes or have concerns about your menstrual health.
