The blastocyst takes another 4 to 6 days to fully embed or 'implant' in the woman's endometrium. The implantation process takes about 6 days to complete (finishing about 12 days after fertilisation, or about 2 days before the woman's next period would have been due). Once the blastocyst is fully implanted, the mother's body starts to provide the developing baby with nourishment to continue to grow. Up until this time the baby has been nourished by glucose secreted from the lining of the fallopian tubes and the uterus.
