Week 5

I have been feeling pretty good. I have been cramping a bit and have been a little tired but that is about it. I will be seeing Dr. Lei every week for my first trimester. I was having really bad back pains last Friday and she totally got rid of them. Woo HOO! You rock Dr. Lei! I worked an 8 hour wedding Saturday and felt great. We signed up for baby center and it was so fun getting the email about our baby today. I wanted to share what Poppy Seed is doing this week. Your pregnancy: 5 weeks How your baby's growing: 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. Ah it is just so amazing. I still can't believe we are going to have a sweet little baby in July :) -Sarah
