Week 4 poppyseed
The blastocyst is now officially considered an embyo and is busy implanting into the lining of your uterus where the placenta will continue to develop.
Week5 apple seed
At this stage your embryo is dividing into three layers of cells. The top layer will eventually become the central nervous system: the brain, spinal cord, spinal nerves, and backbone. The middle layer will develop into the circulatory system and the bottom layer is where the lungs, intestines, thyroid and other major internal organs will develop.
Week 6 small pea
Your baby is rapidly growing and will triple in size this week. Basic facial features such as eyes and ears are becoming more developed and the neural groove will have closed by this time. The tiny heart is starting to pump blood. Along the midline, 40 tiny blocks of tissue are developing which will eventually become the backbone, ribs, and muscles of your baby's back and sides.
Week 7 blueberry
This week your baby's brain is becoming more complex and is developing cavities and passages vital for circulating spinal fluid. Your baby's face is also becoming more defined with the lenses of the eyes and middle part of the ear forming. Tiny arms, legs, hands and feet are also just beginning to bud.
