Week 1-2: Conception and Implantation
During the first two weeks of pregnancy, the fertilization of the egg occurs. This is when the sperm and egg come together, creating a zygote. The zygote then divides, forming a blastocyst, which contains an inner cell mass that will eventually become the embryo. The blastocyst travels down the fallopian tube and implants itself into the lining of the uterus.
Week 3-4: Embryo Development
During the third and fourth weeks of pregnancy, the embryo begins to form. The neural tube, which will become the brain and spinal cord, begins to develop. The heart and circulatory system also begin to form, and the embryo starts to grow limb buds, which will eventually become the arms and legs. At this stage, the embryo is only about 1/25th of an inch long.
Week 5-8: Organ Formation
During the fifth to eighth weeks of pregnancy, the embryo starts to look more like a human being. The major organs start to develop, including the lungs, liver, and kidneys. The heart begins to beat, and the circulatory system becomes more advanced. The brain continues to develop, and the eyes, ears, and nose begin to form. By the end of the eighth week, the embryo is now called a fetus and is about an inch long.
Week 9-12: Fetal Growth
During the ninth to twelfth weeks of pregnancy, the fetus continues to grow and develop rapidly. The fingers and toes become more defined, and the nails begin to form. The sex organs begin to differentiate, and your doctor can tell if you are having a boy or girl. The fetus starts to move, and you may be able to feel it kicking. By the end of the twelfth week, the fetus is about three inches long and weighs about half an ounce.
Week 13-16: Facial Features
During the thirteenth to sixteenth weeks of pregnancy, the fetus’s facial features become more refined. The ears move to their final position, and the eyes move closer together. The bones begin to harden, and the fetus starts to suck and swallow. You may be able to hear the baby’s heartbeat using a stethoscope. By the end of the sixteenth week, the fetus is about four to five inches long and weighs about three to four ounces.
Week 17-20: Movement and Growth
During the seventeenth to twentieth weeks of pregnancy, the fetus continues to grow and develop. The baby’s movements become more frequent and stronger, and you may be able to feel it moving regularly. The skin becomes less transparent, and the baby starts to develop a layer of fat. By the end of the twentieth week, the fetus is about six inches long and weighs about ten ounces.
Week 21-24: Senses Develop
During the twenty-first to twenty-fourth weeks of pregnancy, the fetus’s senses begin to develop. The baby’s eyes open, and it can now see light filtering through the womb. The baby can also hear sounds outside the womb, such as your voice and music. The lungs continue to develop, and the baby starts to practice breathing movements. By the end of the twenty-fourth week, the fetus is about twelve inches long and weighs about one pound.
Week 25-28: Brain Development
During the twenty-fifth to twenty-eighth weeks of pregnancy, the fetus’s brain continues to develop rapidly. The baby’s sleep and wake cycles become more established, and it can now blink its eyes. The lungs continue to mature, and the baby’s chances of survival outside the womb increase. By the end of the twenty-eighth week, the fetus is about fourteen to fifteen inches long and weighs about two to three pounds.
Week 29-32: Growth and Development
During the twenty-ninth to thirty-second weeks of pregnancy, the fetus continues to grow and develop. The baby’s bones become stronger, and its skin becomes less wrinkled. The baby’s movements become less frequent as it grows larger and has less room to move. By the end of the thirty-second week, the fetus is about sixteen to seventeen inches long and weighs about four to five pounds.
Week 33-36: Final Stages
During the thirty-third to thirty-sixth weeks of pregnancy, the fetus is now in its final stages of development. The baby’s head becomes more defined, and the hair on its head starts to grow. The baby’s lungs are now fully developed, and it can now breathe on its own. The baby continues to gain weight and grow larger in preparation for birth. By the end of the thirty-sixth week, the fetus is about eighteen to nineteen inches long and weighs about six to seven pounds.
Week 37-40: Full Term
During the thirty-seventh to fortieth weeks of pregnancy, the fetus is now considered full-term and ready for birth. The baby’s organs are fully developed, and it is now capable of surviving outside the womb. The baby continues to gain weight and grow larger until birth. By the end of the fortieth week, the baby is typically between seven to nine pounds and is ready to make its grand entrance into the world.
In conclusion, the baby starts developing in the womb from the moment of conception until full term. It’s important to take care of yourself during pregnancy and provide your baby with the necessary nutrients to ensure healthy growth and development.
