The colour of your menstrual blood can provide clues about your health, although variations in menstrual blood colour are not always indicative of serious health issues.
Menstrual blood differs from person to person and can even change from one cycle to the next. What's normal for you might not be the same as someone else's, and your period blood colour may fluctuate from day one to the final day or from period to period.
We’ll provide an overview of various period blood colours, what's considered normal, and when they tend to occur. This also covers information about levels of flow, irregular period frequencies and health issues that you may need to watch out for.
Here's an overview of what different colours of menstrual blood might indicate:
Bright red
Fresh, bright red blood is typically considered normal and healthy. It usually indicates that the blood is flowing quickly from your uterus, which is common during the early days of your period. This colour suggests a healthy, regular menstrual cycle.
Dark red
Dark red blood is also considered normal, especially toward the end of your period. It may simply indicate that the blood has taken longer to exit your body and has had more time to oxidize, turning it darker. Older blood from your last period cycle may also have this dark shade of red.
Brown
Brown menstrual blood is often seen at the beginning or end of your period. It is usually old blood that has had time to oxidise, which is completely normal.
There’s a but though.
If you consistently experience brown blood throughout your entire period, it might be worth discussing with a healthcare provider as there might be an underlying health issue.
Pink or light red
Light-colored menstrual blood can occur for various reasons, including hormonal fluctuations or a lighter flow. If it's an occasional occurrence, it's usually not a cause for concern. However, if you consistently have very light-coloured or pinkish blood and experience other unusual symptoms, it's best to consult a healthcare provider.
Greyish or grey
Greyish menstrual blood is uncommon and can sometimes indicate an infection, such as bacterial vaginosis. If you notice greyish blood along with a foul odour, itching, or irritation, you’ll need to see a healthcare provider for evaluation and treatment.
Green or yellow
Green or yellowish menstrual blood is highly unusual and could suggest an infection or a more serious health issue. Infections, such as sexually transmitted infections (STIs), can sometimes cause these colours.
If you observe green or yellow menstrual blood, especially if it's accompanied by a fever, pain, or other symptoms, seek immediate medical attention.
The colour of menstrual blood can offer some insights into your health but, it's just one factor to consider. Other symptoms, such as pain, irregularity, or changes in flow, should also be taken into account.
If you have concerns about the colour of your period blood or any other period issues, it's advisable to seek medical attention. They can provide you with personalised guidance and perform necessary tests to determine if there are any underlying health concerns.
