What Colour Should Your Period Blood Be?
Period blood colour can vary throughout your menstrual cycle, and these changes can provide valuable insights into your overall health. The colour of your menstrual blood is influenced by several factors, including the rate at which the blood exits your body and the amount of time it has to oxidise. Fresh blood that leaves the body quickly tends to be brighter in colour, while older blood that takes longer to exit the body may appear darker.
Understanding why these changes occur can help you monitor your menstrual health more effectively. Variations in blood colour are typically normal, but certain changes can signal underlying health issues that may require medical attention.
Why Does Period Blood Change Colour?
Period blood colour changes are a normal part of the menstrual cycle. These changes occur for several reasons, including how fast the blood exits your body, how long it has been in the uterus, and whether it has mixed with other bodily fluids. Blood that leaves the body quickly will appear brighter, while older blood may turn darker as it oxidises.
The colour variations throughout your period can also be influenced by factors such as hormonal changes, the flow rate, and the general health of your reproductive system.

Common Period Blood Colours and Their Meanings
Bright Red
Bright red period blood is often seen during the heaviest days of your period. This colour indicates that the blood is fresh and is being expelled from the body quickly, giving it little time to oxidise. Bright red blood is usually a sign of a healthy, regular flow.
However, if you experience consistently heavy bleeding or blood clots, it could be a sign of menorrhagia, a condition characterised by excessively heavy periods. In such cases, it is advisable to consult a healthcare provider for further evaluation.
Dark Red
Dark red blood is common, especially during the later stages of your period or when you first wake up in the morning. This colour indicates that the blood has had more time to oxidise before leaving the body. It may also appear at the beginning or end of your period when the flow is slower.
Postpartum bleeding, known as lochia, also tends to be dark red initially before gradually lightening. If you notice this colour at other times, it is generally normal but should be monitored for any unusual patterns.
Dark Brown or Black
Dark brown or black blood typically indicates older blood that has taken longer to exit the body. This colour is often seen at the beginning or end of your period and is usually nothing to worry about.
However, dark brown or black spotting outside of your regular cycle could indicate other conditions, such as hormonal imbalances or the presence of fibroids. If you experience this type of spotting along with other symptoms, it is important to seek medical advice.
Less Common Period Blood Colours
Pink
Pink period blood often occurs when your menstrual blood mixes with cervical fluid, lightening the colour. This can happen when your flow is light, such as at the beginning or end of your period. Pink blood may also be a sign of low oestrogen levels, which can cause the uterine lining to shed irregularly.
Anaemia, a condition caused by low iron levels, can also lead to pink period blood. Iron deficiency affects the colour of your blood, making it lighter. If you suspect you may be anaemic, it is important to consult a healthcare provider for appropriate testing and treatment.
Orange
Orange menstrual blood may be a result of your blood mixing with cervical fluid. While this can be normal, orange blood may also indicate an infection, such as bacterial vaginosis or a sexually transmitted infection like trichomoniasis. If you notice orange blood along with symptoms like itching, an unusual odour, or discomfort, it is crucial to consult a doctor.
Grey
Grey period blood is usually a sign of an infection, such as bacterial vaginosis. This colour is concerning and should not be ignored. Grey discharge, especially if accompanied by a foul smell, itching, or burning during urination, requires immediate medical attention.
In some cases, grey blood may indicate a miscarriage, particularly if it is accompanied by cramping and pain in the lower abdomen. If you experience these symptoms, it is vital to seek medical care as soon as possible.
When to Seek Medical Advice Based on Colour Changes
While it is normal for period blood to change colour throughout your cycle, certain changes may warrant a visit to the doctor. If you notice any of the following, it is advisable to seek medical advice:
- New or unusual discharge, particularly if it is grey, orange, or accompanied by other symptoms.
- Irregular periods that vary significantly in length, heaviness, or consistency from one month to the next.
- Bleeding after menopause.
- Missing three or more periods in a row.
- Itching, burning, or a foul-smelling vaginal odour.
Tracking your menstrual health and being aware of changes in your period can help you catch potential issues early.
Tips for Monitoring and Maintaining Menstrual Health
Maintaining a healthy menstrual cycle involves more than just monitoring the colour of your period blood. It is essential to pay attention to the overall length, flow, and regularity of your cycle. Keeping a menstrual diary can help you notice any patterns or changes that may require medical attention.
Additionally, diet and lifestyle play a significant role in menstrual health. Eating a balanced diet rich in iron, vitamins, and minerals, staying hydrated, and managing stress can all contribute to a healthier cycle. Regular exercise, appropriate for each phase of your menstrual cycle, can also support overall menstrual health.
