Implantation bleeding is defined as a small amount of light spotting or bleeding. It typically occurs about 10 to 14 days after conception. Implantation bleeding is common, and it usually isn't a sign of a problem. Implantation bleeding is thought to happen when the fertilized egg attaches to the lining of the uterus. ©Dr. Google
