Introduction

Pregnancy is a beautiful journey where a tiny cell grows into a fully-formed baby. The process of pregnancy is a complex one, involving the growth and development of the baby, the placenta, and the maternal organs. Understanding how a baby develops during pregnancy is essential for expecting mothers. It helps them prepare for the arrival of their little one and take the necessary precautions to ensure a healthy pregnancy.

Week 1 to Week 4

The first four weeks of pregnancy are crucial in the development of the baby. During this time, the fertilized egg divides into multiple cells and forms a ball called a blastocyst. The blastocyst then implants itself into the uterus, where it starts to grow. By the end of the fourth week, the baby’s neural tube, which eventually becomes the brain and spinal cord, begins to form.

Week 5 to Week 8

During weeks five to eight, the baby starts to take shape. The heart begins to beat, and tiny arms and legs start to form. The baby’s facial features, such as the eyes, nose, and mouth, also start to develop. At the end of the eighth week, the baby is officially called a fetus.
