Brown Period Blood: What It Means

Brown period blood might look strange, but it’s usually normal and not something to worry about. This color often occurs at the beginning or end of a period when the blood is moving more slowly. Conditions like irregular periods or endometriosis can also result in brown blood. In most cases, it’s simply a sign that the blood has taken longer to leave the body and has had time to oxidize. Here’s what you need to know about brown period blood.

Why Is My Period Blood Brown?

Old Blood

According to Natalia Hapych, a family doctor, “Brown period blood is often just older blood that has taken longer to exit your body.” This happens more frequently at the beginning or end of your period.


The brown color is usually due to oxidization. This means that the blood has reacted with oxygen in the air. It’s similar to how an apple turns brown after you cut it and leave it out.
