Period Colours, Decoded
By the eva team · · 2 min read
Period blood doesn't always look the same from one day to the next. It can be bright red, dark red or brownish, and these changes are often linked to how long the blood has been in the uterus and vagina before leaving the body. Learn what different period colours usually mean and when a colour change may be worth checking.
1. Why Does Period Blood Change Colour?
Ever noticed that your period blood doesn't always look the same? It can change colour throughout your period, and that is often completely normal. Let's decode the most common colours and what they may mean.
2. Bright Red? Often A Fresh Flow
Bright or vivid red period blood usually means the blood is leaving the body relatively quickly. You may notice this colour when your flow is more active, especially during the earlier or heavier days of your period.
3. Dark Red? It Can Be Normal Too
Dark red or deep burgundy period blood is also common. It can happen when blood takes longer to leave the body, allowing its colour to become darker. You may notice this later in your period or after a heavier flow.
4. Brownish Blood? Think Older Blood
Brown or brownish period blood often happens when blood takes longer to leave the body and has had more time to change colour. You might notice it at the beginning or end of your period, or when your flow is lighter.
5. Your Period Can Have More Than One Colour
It is normal for period blood to change colour during the same period. You might see brighter red blood on one day and darker red or brownish blood on another. Your flow can also change from heavier to lighter as your period continues.
6. Colour Alone Doesn't Tell The Whole Story
Period colour is only one part of the picture. It is also helpful to notice your flow, how long you bleed, whether you have pain and whether anything feels unusual for you.
7. When Should You Pay Attention?
A colour change by itself is usually not a reason to panic. But if bleeding is very heavy, lasts unusually long, comes with severe pain, or you notice other symptoms that concern you, it is a good idea to talk to a trusted adult or healthcare professional.
8. Different Colours. Same Body.
Bright red, dark red and brownish blood can all be part of a normal period. Instead of worrying about one colour, learn your own pattern and pay attention to changes that feel unusual for you.
