Are you curious about how an unborn baby develops? It’s an amazing journey that starts from a single cell and ends with a fully-formed baby ready to enter the world. In this article, we will guide you through the stages of fetal development and explain what happens every step of the way.

Week 1-4: Conception and Implantation

The journey begins when a sperm fertilizes an egg, creating a single cell called a zygote. The zygote then divides and becomes a ball of cells called a blastocyst. By the end of the first week, the blastocyst attaches itself to the uterine lining, known as implantation.

Week 5-8: Embryonic Period

During the embryonic period, the blastocyst continues to develop into an embryo. By the end of the fifth week, the embryo is about the size of a grain of rice and has already formed the brain, spinal cord, and heart. During the sixth week, the eyes, ears, arms, and legs begin to form. By the end of the eighth week, the embryo is considered a fetus.

Week 9-12: Fetal Period

During the fetal period, the fetus continues to grow and develop. By the end of the twelfth week, the fetus is about three inches long and weighs about half an ounce. The fetus is also able to move its arms and legs and can even suck its thumb. By the end of the twelfth week, the fetus has all of its major organs and structures.
