At this stage, your baby is about the size of a blueberry, measuring approximately 0.51 inches (1.3 cm) long from crown to rump, and weighing around 0.04 ounces (1 gram). Although it’s still tiny, your baby is already starting to look like a human being, with a head, body, and limbs taking shape.

Brain and Nervous System Development
Your baby’s brain and nervous system are developing at an incredible pace during the seventh week of pregnancy. The neural tube, which will eventually become the brain, spinal cord, and other essential nervous system tissues, is now fully formed. Moreover, your baby’s brain is starting to develop specific regions that will be responsible for different functions such as movement, sensation, and perception. Although your baby’s brain is still small, it is already generating electrical activity that can be detected by an electroencephalogram (EEG).
Heart and Circulatory System Development
Another critical milestone that takes place during the seventh week of pregnancy is the development of your baby’s heart and circulatory system. By now, your baby’s heart is beating at an impressive rate of approximately 150 beats per minute, which is about twice as fast as your own heart rate. The heart is pumping blood through your baby’s growing body, and the circulatory system is starting to form networks of blood vessels that will supply oxygen and nutrients to all organs and tissues.
Facial and Body Features Development
As your baby’s brain, heart, and circulatory system are developing, so are the facial and body features. During the seventh week of pregnancy, your baby’s eyes, nose, mouth, and ears are starting to take shape. The eyelids, which have been fused shut until now, are beginning to separate, and the retina is forming. Your baby’s nose, lips, and tongue are developing, and tiny earlobes are starting to emerge. Moreover, your baby’s body is elongating, and the arms and legs are becoming more distinct, with fingers and toes starting to form.
Other Developmental Milestones
Along with the above developmental milestones, your baby is undergoing many other changes during the seventh week of pregnancy. The digestive system is starting to form, with the esophagus, stomach, and intestines taking shape. The kidneys are also developing, and they will soon start producing urine, which will be excreted into the amniotic fluid. Furthermore, your baby’s liver is producing red blood cells, a function that will be taken over by the bone marrow later on.
Conclusion
As you can see, your baby is going through many exciting changes during the seventh week of pregnancy. Although it’s still early days, your little one is growing and developing at an impressive rate, and it won’t be long before you can see its features in more detail through an ultrasound scan. So, sit back, relax, and let your baby do its thing as it prepares to enter the world.
