Doctor's answer:
The fertilized egg generally implants in the uterus about 14 days after fertilization. This process is called pregnancy. If implantation occurs but is then expelled from the body, it is called a miscarriage. If it does not miscarry, it will not naturally be expelled from the body, so there is no need to worry.
