There’s usually a variety of health conditions that affect your menstrual cycle, not just the color of the blood. But sometimes the color of your menstrual blood can be a scary thing if you don’t have prior knowledge. That’s why we’re here to help.
Here’s what the colours of your menstrual blood mean:
Black/Dark Brown Menstrual Blood
This is usually the left over of blood from your previous cycle or blood that comes out first if you’ve had a late period. Blood gets oxidized when it stays in your uterus for long and then turns black, same as the blood that drops on your cloth turns dark brown or black over time. The use of contraceptives can also make your period blood darker.
Bright Red Menstrual Blood
After the first blood comes out it basically becomes a gush fest as your flow gets heavier because the uterine walls shed faster. This period blood does not stay in the uterus for long and so has not had time to oxidize so its bright red in color and looks like what you think is fresh and healthy.
This is usually called spotting and happens outside your regular period. Spotting can be caused by taken emergency contraceptives and can sometimes occur during ovulation. Spotting during ovulation is usually called ovulation bleeding.
If you have any concerns about the colour of your period blood, please see a doctor.
