It takes 6 to 10 days for implantation to occur after fertilization of the egg, as stated by BabyCorner. Implantation occurs after the embryo becomes a blastocyst, a cluster of multiplying cells.
The fertilized egg will attach itself to any side of the uterine wall. After fertilization, the egg stays in the fallopian tube for up to three days before entering the uterus. During the process of implantation, a woman may experience cramps, bleeding, rise in temperature and temperature dip. However, these signs may be hard to be noticed. There is no cause of despair if a person does not experience any of these signs.
