Illustration of a pregnancy in the third week (the first week after conception). An egg is released from the ovary and travels through one of the fallopian tubes where it is fertilized by sperm to form a zygote, a single cell carrying chromosomes from both the mother and father. The fertilized egg then implants itself into the wall of the uterus.
