Pregnancy Week by Week – Week 5: The baby’s brain is making its first appearance.

The first month of pregnancy is now behind you. It is quite possible that you might not even know that you are pregnant. Yet your little baby, still in its embryonic stage, is busily growing and developing. What is going on in Week Five?

What is happening with your Baby?

The kidneys make their first appearance in week five yet do not function for another month. Your baby’s brain divides into the forebrain, midbrain and hindbrain in this week. The forebrain section begins to develop into your baby’s eyes and nose.

Your baby’s heart is continuing to develop all of its four chambers. Many of the organs in the digestive tract such as the esophagus, stomach, liver, pancreas and gall bladder are also developing. The beginnings of the umbilical cord can be seen in week five. The respiratory tract which formed in week four is also growing and developing.

What is happening with You?

You are now several weeks past your due date. You may be having some sensations of fullness or bloating. It is possible that you might be feeling some morning sickness.

If you visit your health care provider he or she might be able to see a softening of the cervical tip on a pelvic exam toward the end of the fifth week. This is called “Goodell’s sign.”
