This stage includes the first three months of your baby's development. After conception, the fertilized egg moves down the fallopian tubes and divides into two cells. From two cells, it divides into four, eight and so forth until it forms a solid ball of cells. The ball of cells then enters the uterus and attaches itself to the uterine wall. The ball of cells is referred to as the embryo at this stage. It will develop into a baby and to protect the baby the ball of cells also develops into umbilical cord, the placenta and the amniotic sac. As the ball of cells attaches itself to the uterine wall, the surrounding tissue produces hormones to support the pregnancy. This stage occurs during the first three weeks. Here are the lists of your baby's development starting from week 4:
Week 4: the embryo starts to develop major organ systems like brain and spinal cord; nervous systems; muscles and blood.
Week 5: during this week, you can feel the first heartbeat of your baby. Your baby's length reaches 2 mm.
Week 6: in this week, the embryo starts to develop facial features and reaches 6 mm in length.
Week 7: your baby's spinal cord and brain are developing and it lies within a sac of membranes. The baby will be supported by amniotic fluid. During this week, nostrils and lips of your baby appear and the eyes can be seen under the skin.
Week 8: you baby's limbs appears during this week while its hands and feet are taking shape. Your baby now reaches 1.3 cm in length.
