5 weeks

According to babycenter.com here is what is going on with our little one this week;

Deep in your uterus your embryo is growing at a furious pace. At this point, he's about the size of a sesame seed, and he looks more like a tiny tadpole than a human. He's now made up of three layers — the ectoderm, the mesoderm, and the endoderm — which will later form all of his organs and tissues. The neural tube — from which your baby's brain, spinal cord, nerves, and backbone will sprout — is starting to develop in the top layer, called the ectoderm. This layer will also give rise to his skin, hair, nails, mammary and sweat glands, and tooth enamel. His heart and circulatory system begin to form in the middle layer, or mesoderm. (This week, in fact, his tiny heart begins to divide into chambers and beat and pump blood.) The mesoderm will also form your baby's muscles, cartilage, bone, and subcutaneous (under skin) tissue. The third layer, or endoderm, will house his lungs, intestines, and rudimentary urinary system, as well as his thyroid, liver, and pancreas. In the meantime, the primitive placenta and umbilical cord, which deliver nourishment and oxygen to your baby, are already on the job.

As for me, nausea has finally set in!  I spent Monday night heaving in front of the toilet, thinking I was going to get sick every where.  I'm nauseous all day, every day.  Foods that I used to eat daily now disgust me... particularly peanuts and bananas.  I'm living off of saltines, gingerale, ginger tea, chamomile tea, grilled cheese and chicken soup (being a vegetarian went out the window when I realized that real food wasn't acceptable).  Hopefully I'll start feeling better soon, so I can get the poor baby of ours some nutrition.  At least I'm taking pre-natal vitamins.  Due to not being able to eat, I lost 2.5 of the 4 pounds that I had already gained.
