Period blood colours and meaning

Menstruation also called period is the process of discharging through the vagina, blood and other materials from the lining of the uterus at about one monthly interval. The fact that menstrual blood contains cells from the lining of the uterus is only one of the things that makes it different from the blood that you see when you cut your finger.

It is always important to recognize and understand the signs and colors of your menstruation. The colours can range from black, orange, bright red and more!

Black blood

Black period blood comes as a result of blood that’s been in your body for a long time. Typically occurs after a delayed period. Some women also tend to see black blood at the very beginning of their period when the lining of your uterus is starting to break down. So when you see black blood during your period, you don’t need to worry about it.

Grey blood

Grey period blood usually signifies bacterial vaginosis infection, which occurs due to an imbalance between helpful and unhelpful bacteria in the vagina.

Pink blood

Pink period blood likely indicates that the blood has mixed with your cervical fluid, creating a lighter shade. It can also be as a result of low estrogen levels, especially if it’s accompanied by a lighter-than-usual flow, or if you work out a lot.

Orange blood

Orange period blood can also be the sign of period blood mixed with cervical fluids, so you might see orange blood for the same reasons you see pink blood. However, bright orange menstrual blood can also indicate an infection.

Bright red blood

Bright red blood indicates a healthy and regular period. Of course, everybody’s “normal” will look different, but generally speaking, a consistently bright red flow is a signal that everything’s working as it should down there!






Changes in the colour of your period blood are not anything to worry about. But do pay attention to the volume of your flow, changes in cycle length, and pain or any bleeding that doesn’t have a pattern, as these can indicate underlying conditions.
