Patient's question:
Does implantation failure of the fertilized egg lead to miscarriage?Doctor's answer:
If implantation of the fertilized egg fails, it may be expelled from the vagina along with the endometrium or secretions, or naturally absorbed by the body. Since sperm and eggs can only be seen as tadpole-like structures under high magnification, you cannot see the fertilized egg being expelled with the naked eye. The situation you described is a biochemical pregnancy, which is a type of miscarriage caused by the failure of the fertilized egg to implant. The amount of bleeding during this miscarriage is similar to that of a menstrual period. If there are no discomforts, it can be temporarily observed, and the bleeding will gradually decrease and stop.
