Implantation bleeding typically appears as light spotting or very light bleeding that is usually pink, light rust, brown, or dark brown in color. It is much lighter than a regular menstrual period and often only shows as a few drops or smears on toilet paper, underwear, or a pantyliner. The bleeding is usually not heavy enough to soak through a pad or underwear and does not include clots, which are common in menstrual bleeding. The spotting may last for a day or two and can be accompanied by mild or very light cramping, which is less intense than period cramps

. In summary, implantation bleeding looks like:

• Light pink, brown, or rusty-colored spotting
• Very light flow, just a few drops or smears
• No clots present
• Lasts 1-2 days
• Mild or no cramping

This bleeding occurs when a fertilized egg attaches to the uterine lining, causing small blood vessels to break and bleed slightly

. If bleeding is heavy or accompanied by severe pain, consulting a healthcare professional is advised.
