Every new life starts as a single cell. After the sexual intercourse, when a sperm from the father’s semen enters the ovum of the mother, fertilization takes place. Pregnancy begins when a fertilized egg attaches itself to the lining of the uterus.
During the first two months of pregnancy, the developing baby is called embryo. After this period until the birth 9 months, the developing baby is called a foetus. After two months, the foetus, though only about 2.5 cm in length can move its head, mouth, arms and legs. The child develops in about nine months in the womb. After nine months, a new child is born on earth.
