In the first nine weeks of pregnancy, the fertilized egg travels to the uterus and begins to implant. The cells inside the egg start to form groups, and the embryo starts to grow in size. By the tenth week, the baby will have the size and shape of a grape, and the cells inside the egg will start to create organs. By the twelfth week, the baby will have the size of a raisin and weigh a few grams.

• 00:00:00 Embarazo: In the first nine weeks of pregnancy, an unborn baby's "plate" - or fertilized egg - travels to your uterus. This process is called implantation. In just a few days, the cells that are present in the egg will begin to form groups, and the embryo will start to grow in size. By the tenth week, your baby will have the size and shape of a grape, and the cells inside the egg will start to create organs - the brain and spinal cord. By the eleventh week, your baby will have the size of a seedpod, and he or she will start to absorb nutrients and oxygen through the newly formed placenta. By the twelfth week, your baby will have the size of a raisin and weigh about a few grams. It's amazing how quickly a cell can turn into a body - and the unique body of a baby!
