Your baby -- now officially an embryo -- is about the size of a poppy seed.




How your baby's growing:
This week marks the beginning of the embryonic period. From now until ten weeks, all of your baby's organs will begin to develop and some will even begin to function. As a result, this is the time when he'll be most vulnerable to anything that might interfere with his development.

Right now your baby is an embryo the size of a poppy seed, consisting of two layers: the epiblast and the hypoblast, from which all of his organs and body parts will develop.

The primitive placenta is also made up of two layers at this point. Its cells are tunneling into the lining of your uterus, creating spaces for your blood to flow so that the developed placenta will be able to provide nutrients and oxygen to your growing baby when it starts to function at the end of this week.

Also present now are the amniotic sac, which will house your baby; the amniotic fluid, which will cushion him as he grows; and the yolk sac, which produces your baby's red blood cells and helps deliver nutrients to him until the placenta has developed and is ready to take over this duty.
