Your Baby's Growth and Development
At 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. Jen here: And they had better not be like O+ Abby and cause me to have another dose of Rhogam - that shot hurts! 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. Jen here: Yay for teeth! Unless they are biting teeth, and then we'd rather not have them. 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!
Your Growth and Development
You still aren't showing much if at all by 7 weeks pregnant (Yeah... right! Just ask Sarah or any of the other Myers clan), though you might start noticing a small pooch look to your lower abdomen. You may find that your favorite pair of jeans is much less comfortable during pregnancy at 7 weeks than your worn pair of baggy sweatpants. You might start thinking about maternity clothes. (Thinking... as in deciding which pair of maternity jeans to wear today?) Still, by and large most people will not be able to detect your pregnancy yet as you won't start really showing until many weeks in the future. (False)
