Week Seven

I copied this from a website. It is amazing that even though the baby is so tiny, so much is going on!

How Big is the Baby at Seven Weeks Pregnant?
During pregnancy week 7 your baby will grow tremendously, up to 13 mm in length! Your baby is much closer to the size of a large blueberry or small grape by 7 weeks pregnant than a pea.
Your Baby's Growth and DevelopmentAt 7 weeks pregnant facial features become more prominent in your newborn. Upon close investigation you may be able to discern a mouth and even a tongue (you actually can't see the tongue, but it is forming inside your baby!). During pregnancy week 7 your baby's eyes will also start to become more fully formed, and now have a retina and lens attached. The major muscle systems in the body also continue to develop during pregnancy week 7, and your baby begins to produce his own blood type. Your baby's movements will be uncoordinated at best at this point during pregnancy, but rest assured your little one is squirming about his new home.
If you were to look directly at your baby you would still be able to see slight webbing in the fingers and toes during pregnancy 7 weeks. Teeth are also starting to form on the inside of your baby's mouth, and thin veins start to peer out from beneath your baby's skin. Your baby's intestines and appendix should be formed by now. By this time your baby's liver is working diligently to start producing red blood cells. Your baby should be bouncing right along in his comfy and warm home
