Typical Period Blood Colours

It’s normal for the colour and consistency of period blood to vary at different stages during your “time of the month.” In some cases ovulation, hormonal changes, and various health conditions can affect the colour and texture of period blood. It’s important to pay attention to your period blood colours because they may actually be warning you about a problem.

1. Black/Brown/Dark Red

Black/brown blood with a thick consistency is completely normal to observe at the beginning or end of your period. This usually signifies old blood that has taken longer to leave the uterus and has had time to oxidize before leaving the body.

Consult your healthcare provider if: you see brown or black blood for more than two days, towards the end of the period.

2. Bright Red

Indicates fresh period blood and a steady flow. A period may start with bright red blood when the uterine lining sheds faster and the flow is heaviest.

3. Pink

Pink period blood (spotting) can happen when the blood is mixed with cervical fluid. Using birth control can also lead to a lighter flow, creating lighter period blood colours.

Consult your healthcare provider if: you experience pink blood (or any blood) during pregnancy as it may indicate a miscarriage.

Abnormal Period Blood Colours

Some period blood colours or vaginal discharge colours are cause for alarm and should immediately be brought to the attention of your healthcare provider. Watch out for the following:

4. Gray

Gray discharge during menstruation can point towards an infection known as bacterial vaginosis.

5. Orange

Orange discharge during menstruation often indicates infections such as bacterial vaginosis or trichomoniasis.
