While you won’t notice any changes in your belly at 4 weeks, during weeks 4-5 of your pregnancy, the embryo develops within the lining of the womb. Your embryo is about the size of a poppy seed and is about 2 mm long. During this stage, the outer cells form links to be able to reach the mother’s blood supply. At the same time, the inner cells merge to create two layers at first and later become three layers.

These layers grow and develop to become different parts of the baby’s body:

• The inner layer formed grows into the baby’s breathing and digestive system.
• The middle layer forms the heart, blood vessels, muscle, and bones.
• The outer layer grows into the brain and nervous system as well as eye lenses, tooth enamel, skin and nails.
