My Pregnancy-4 Weeks

*Originally written on Jan. 20, 2010* ALMOST done updating...promise!

How your baby's growing:

This week marks the beginning of the embryonic period. From now until 10 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 she'll be most vulnerable to anything that might interfere with her 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 her 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 her as she grows; and the yolk sac, which produces your baby's red blood cells and helps deliver nutrients to her until the placenta has developed and is ready to take over this duty.

Yay, our wee babe is an embryo now! Very exciting. So far I am still cramping on and off. No spotting which is great. I am nauseous on and off, but am expecting that. And my chest is hurting a little more each day. It is so awesome to not be on my period, I am loving it, haha. :) I cannot wait to tell our families next weekend!!

I so remember being right where you are. So nerve racking and yet exciting. I am happy to re-live it again through you.
