What happens if an egg is fertilized but doesn't implant?

If the blastocyst doesn't implant in the person's endometrium, pregnancy will not occur. For implantation to occur, hormones trigger a process called hatching. The blastocyst sheds its clear outer membrane. Hatching occurs one to three days after a blastocyst enters their uterus.
