As soon as you find out you are pregnant, you start to wonder how your baby is developing inside you. The first trimester is a crucial time for your baby’s growth and development. In this article, we will take a closer look at how much does a baby develop in the first trimester.

Week 1-2: Conception

The first two weeks of pregnancy are considered the preconception period. It is during this time that your body prepares for ovulation and conception. If you have sex during this time, sperm can fertilize the egg as soon as it is released. The fertilized egg then travels to the uterus and implants itself in the lining.

Week 3-4: Formation of the Embryo

By the third week of pregnancy, the fertilized egg has divided into multiple cells and is now called a blastocyst. The blastocyst attaches itself to the wall of the uterus and starts to form the embryo. During the fourth week, the baby’s brain, spinal cord, and heart begin to form.

By the fifth week of pregnancy, the baby’s heart is beating and can be seen on an ultrasound. The baby’s facial features, such as the eyes, nose, and mouth, also begin to form. In the sixth week, the baby’s major organs, such as the liver, kidneys, and lungs, start to develop.

Week 7-8: Fingers and Toes Form

During the seventh week, the baby’s arms and legs begin to grow longer, and fingers and toes start to form. The baby’s brain also continues to develop rapidly. By the eighth week, the baby’s eyelids are forming, and the baby can make small movements, although these movements are not yet noticeable to the mother.

Week 9-10: Baby Becomes a Fetus

By the ninth week, the baby’s tailbone starts to disappear, and the baby is officially considered a fetus. The baby’s organs and tissues continue to mature, and the baby’s bones begin to harden. By the tenth week, the baby’s fingerprints are formed, and the baby can move its limbs more freely.

Week 11-12: Baby’s Gender is Determined

During the eleventh week, the baby’s sex organs start to develop, and the baby’s gender is determined. By the twelfth week, the baby’s digestive system is starting to work, and the baby can swallow amniotic fluid. The baby’s skin is also becoming less transparent, and the baby starts to look more like a miniature human.
