This week you ovulated and now the moment you’ve been waiting for has finally arrived! Conception has occurred and your soon-to-be-baby has started on its miraculous transformation from egg to baby boy or girl! Once the winning sperm has penetrated the egg, the egg doesn’t allow any further sperm in. Your now fertilized egg is known as a zygote.
It is at this early stage, from the moment of fertilisation, that your little one’s gender, eye colour, hair colour and other genetically determined characteristics have already been decided.
