Implantation bleeding refers to a minor episode of spotting or bleeding that occurs when a recently fertilized egg embeds itself into the lining of the uterus.
Implantation bleeding is a phenomenon that occurs in early pregnancy and is experienced by approximately one-third of women, according to information from the American Pregnancy Association.
The duration of implantation bleeding can vary from person to person. Some individuals report that it lasts for only one day, while others claim it persists for three or four days.
