The First 9 Weeks

Day 1 - At conception, the sperm joins with the ovum (egg) to form one cell that contains the complex genetic blueprint for every detail of human development. At this moment the child’s sex, hair and eye color, height, and skin tone are already decided. Within about three days after conception, the fertilized egg is dividing very fast into many cells. It passes through the fallopian tube into the uterus, where it attaches to the uterine wall. The placenta, which will nourish the baby, also starts to form.

Day 21 – The heartbeat begins.

Week 4 - The beginning of the spinal cord, muscles, and nerves become apparent as the lungs, stomach and liver start to develop. The amniotic sac and placenta are in place and providing nourishment to the embryo.

Week 6 - The eyes begin to form and the extremities can be seen in much more detail, including all ten fingers. The embryo is now moving and responds to touch.

Week 8 - The baby is now a little over half an inch in size. Eyelids and ears are forming, and you can see the tip of the nose. The arms and legs are well formed. The fingers and toes grow longer and more distinct.
