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.

  1. hi ann,

    ang galing no, the first thing that develops in our babies talaga is the heart, kaya this is a very crucial stage. Stay as calm as you can and keep yourself away from any stresses. I suggest you do the same thing I’m doing now, listen to classical music- kasi it stimulates the baby daw inside.
    By the way, if you can download “In the Womb” (National Geographic Channel)do so, you’ll learn a lot from there kasi para siyang reality TV, you’ll see the actual development of the baby from the inside, from the time na nag-fertilize na yung sperm n egg hanggang birth… you’ll be amazed!!

    Happy pregnancy fellow mommy-to-be!!!!

  2. Oh, wow, congratulations po. 🙂

  3. @ Ann, sige nga at ita-try ko i-download yan sinasabi mong documentary. Pero mukhang napanood ko na ata yan … kaso yung version naman ng Discovery ata yun hehehe!
