Has Your Period Blood Ever Changed Colour? Here’s What It’s Trying To Tell You

It’s not uncommon to discuss your period; in fact, it’s encouraged. However, when we sit down with our friends, we’re typically talking about PMS, period pyjamas, birth control or whether our cycle is late, early, light, heavy or currently non-existent. One period-related topic rarely discussed at the dinner table however, is the ever-changing colour and texture of the blood and what it’s trying to tell us.

What does it mean if the colour of your period blood changes?

No two periods are the same, whether that’s from month to month or person to person. Even during the same cycle, period blood can change in colour and texture.

Factors that influence these changes can include anything from hormones, diet, age and lifestyle to flow, infections or pregnancy.

Here’s what each colour of blood might be trying to tell you…

Here’s a broad outline of what each shade of blood might signify as guided by The Cleveland Clinic.

Even though we don’t advise taking these guidelines as gospel, it’s helpful to be aware of the changes taking place during your cycle and use them as a guide to understanding your menstrual health. If any changes persist or seem out of the ordinary, we recommend consulting your doctor.


Blood clots during a period are representative of a heavy flow. Minor clotting which contain visible pieces of tissue mixed amongst blood are normal and should not trigger concern.


Blood that appears black in colour can often signify old blood or blood that has taken longer to leave the uterus and oxidise. This is common at the beginning or the end of a period. When blood has time to oxidise, it initially turns dark red, brown and then eventually turns to a shade of black.

Brown to dark red

Similarly to the above, shades of brown to dark red are symbolic of old blood. Other symptoms of brown blood, or brown spotting can be representative of an early pregnancy, otherwise known as “implantation bleeding.”

Bright red

Bright red blood is fresh and is typically indicative of a regular flow. 


When blood appears to be a lighter pink hue, this can often indicate the mixture of blood with cervical fluid. Pink blood may occur when taking birth control pills that lower estrogen levels.


Like the pink-hued appearance of blood, when mixed with cervical fluid, it may also appear to have an orange tinge. Though if orange-hued blood continues, seek the advice of your doctor as orange blood can also be associated with bacterial vaginosis.

  1. 8 years ago mine became like water and I had no warning when it might arrive as I could no longer call it my monthly as it the gap between started to get smaller and smaller. I went to the Doc and told her that I was bleeding ALL THE TIME. I think she thought I was being overly dramatic so she gave me a calendar to fill out. When i returned to her a month later she was stunned to she that I had only had 2 days where I wasnt bleeding. With lots of tests it was finally discovered that I had several tumours and a polyup in my utereus. I was shocked at the word tumour but it turned out that they were not the concern. The polyup on the other had was pre canacerous so i was off for a surgery and to live to tell the tale.

  2. So glad that I don’t have my Periods anymore, but remember the different Shades of Period Blood. So glad that I don’t have to worry anymore and have to go to the Doctor to find out if it was normal.

  3. It’s good to know what’s normal & what needs discussing with your doctor. When I was 40, I started getting light, mid-cycle bleeding, which didn’t concern me greatly. I mentioned it to my doc, who said since I’m 40, this could be a sign of cancer! I had it checked out – not cancer & it eventually went away, but it’s something those 40+ need to know.
