TTC Weeks 3-4

Implantation

Implantation is the process by which a fertilised egg, now called a blastocyst, burrows into the lining of the uterus (endometrium) to establish a pregnancy. It typically occurs 6 to 10 days after ovulation. Once the blastocyst embeds successfully, it begins producing the hormone hCG, which signals the body to maintain the uterine lining and support early pregnancy. Successful implantation depends on a receptive uterine lining and a healthy embryo. If the embryo does not implant, the lining sheds and menstruation occurs. This is a natural step that even healthy embryos sometimes do not complete.

What This Means for You

Good to Know

There is no medical intervention to force or confirm implantation at home. If you have had repeated implantation failures during IVF, your specialist at KKH or NUH can investigate uterine lining thickness and other contributing factors.
