My Pregnancy-5 Weeks and 100th Post!

See the big picture

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.

Wow. There is a lot of stuff going on this week. No wonder this is part of the "critical time". The bebe is growing growing growing! So I am not really nauseous yet too badly. I get waves of it on and off, especially in the morning when I am in the shower. I have started eating an apple while I get ready in the morning and by the time I am ready to leave for work and I am SO incredibly hungry. I feel like I am hungry all the time actually, it is odd. Like no matter how much I eat I cannot get completely full! I am gassy too.
My little "bloat bump" is really starting to show too. It is crazy!! The other day my friend Jessica that I work with even told me that "she noticed it when I took my coat off that morning." And that "I was probably not going to be able to hide it for as long as my coworkers did because I am so thin to begin with." I was like OH. CRAP. Haha....that is ok though. I am looking forward to it. I want to look pregnant!! I am so excited. Two more weeks until my first appointment!! :)
