I love the internet.  It’s so chock full of information.

I went to the website www.WhatToExpect.com and signed up for an account.  According to their calculator, I have been pregnant for 4 weeks already, and am now heading into my 5th week, and I am still in my first trimester. 

Here’s what it says BabyCarpio looks like right now:

Week 4: Studio Apartment, Water View


Your little ball of cells is splitting into two groups this week. One will become your son or daughter while the other becomes the placenta — the lifeline that channels nutrients to your baby and carries waste away.
Your baby has found its home — your uterus. Once there, it burrows into your uterine lining and implants — making that unbreakable connection to you that’ll last the next eight months (and a lifetime after that). Once firmly in place, the ball of cells undergoes the great divide — splitting into two groups.  Half (now called the embryo) will become your son or daughter while the other half becomes the placenta — the lifeline that channels nutrients to your baby and carries waste away.
 
Despite its extremely tiny size — no longer than one millimeter and no bigger than a poppy seed (think about that as you eat your morning bagel) — your little embryo is busy setting up house. The amniotic sac that boards your baby (also called the bag of waters) is forming, as is the yolk sac (don’t worry, you’re not having a chicken), which will later be incorporated into your baby’s developing digestive tract.

The embryo now has three distinct layers of cells that will grow into specialized parts of your baby’s body. The inner layer, known as the endoderm, will develop into your baby’s digestive system (with help from that yolk sac), liver, and lungs. The middle layer, called the mesoderm, will soon be your baby’s heart, sex organs, bones, kidneys, and muscles. The outer layer, or ectoderm, will eventually form your baby’s organs and tissues, including the nervous system, hair, skin, and eyes.

On a side note, I feel like my stomach is totally empty all the time and I feel like I want to eat everything in site, but when I see food, suddenly my stomach turns.  I thought I wasn’t supposed to feel nauseous for another few weeks?  Bleh.  But I did read that nausea should be considered a good thing because the baby is developing healthy and it regulates insulin.  Uggh…ask me that in a couple of weeks….
