What Does It Mean When You Bleed Dark Red Blood for Two Days?

Dark-colored blood towards the end of a menstrual cycle indicates the expulsion of older blood and is not a cause for concern, according to WebMD. There are some instances in which this is an indicator of other serious health issues.

Because older blood is not as freshly oxidated, it is typically darker in color and can be dark brown or almost black, explains WebMD. In these circumstances, the dark color is not an issue.

There are some situations in which darkly colored bloody discharge indicates a serious problem, states, Phaa.com.
