It takes roughly about 1 week for the fertilised embryo to travel from the fallopian tubes into the uterine cavity. Afterwards, the fertilised embryo then needs to attach itself to the lining of the womb and this process is called implantation. The lining of the womb is also known as the endometrium.
Meanwhile, the implantation process usually can occur as early as 6 days and as late as 12 days. This is after the process of fertilisation of the embryo in the fallopian tubes .
