Pregnancy - Week 5

Week 5:

This week your baby is about 1-1.25 mm long. The central nervous system, spinal cord, spine, and brain are starting to develop more and take shape.

Your baby's organs are growing and developing rapidly. Her brain is starting to separate into two different lobes.

Also the baby's skeleton is taking shape along with most of the other organs.

The lungs are growing well. They start out forming close to the head of your baby, but as she grows they move down into the chest cavity.

You may be feeling nauseated as well as urinating more. But you may also feel normal still. There is not too drastic a difference of your size.
