Today I hit the 5 weeks prego mark. It’s so funny/frustrating how long and slow the first days/weeks are. You are no bigger than a sesame seed but I feel your effects already and I’m counting down the days until I get to see your little heartbeat to reassure me you’re doing alright in there (13 more days!!!). You gave me a little scare last week when I started spotting so I made the doctor give me some progesterone supplements to make sure your little home was nice and comfy. And guess what? It seemed to work. The spotting stopped, but now I’m all sorts of bloated! I’ll take it though. Anything for you my sweet little souvenir! ♥
Symptoms: Nausea, Bloatedness, Frequent urination, Irritability (oh the mood swings and the tears! Just ask your Daddy!)
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.
