In no time, now you are 5 weeks pregnant. So what happens during this week? Deep in your uterus, your embryo is growing at a fast pace. At this point, a 5 week's embryo is about the size of an orange seed or a grain of rice, and he looks more like a tiny tadpole than a little human. Your little bean is now made up of three layers - the ectoderm, the mesoderm, and the endoderm. It will later form all of his organs and tissues.\r\n\r\n\r\nBaby at 5 Weeks Pregnant\r\nThe amniotic sac which is the house or the home for the embryo floats in a sea of fluid. The embryo is the size of a sesame seed. The neural tube will develop into your baby's brain, spinal cord and nerves.\r\n\r\n\r\nThe neural tube \u2014 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 your little bean skin, hair, nails, mammary and sweat glands, and tooth enamel.\r\n\r\nThe heart and circulatory system begin to form in the middle layer or mesoderm. Your little bean 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 the skin tissue.\r\n\r\nThe third layer, 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.\r\n\r\n\r\nBody Changes\r\n\r\n\r\n\r\nBladder: You may soon start to notice a more frequent urge to pee.
