Period blood can vary in color, with pink, red, and brown being the most common shades. The color can be influenced by several factors, including:
- Flow: At the beginning and end of your period, the flow is lighter, giving the blood more time to oxidize and appear darker.
- How long the blood sits: The longer the blood sits in the uterus and vagina, the darker it will become.
- Iron levels: Low iron levels, or anemia, can result in pink period blood.
While color changes are typically normal, it's important to consult your doctor if you experience unusual changes in your period blood color or if you have any concerns about your cycle.
