Baby development

The development of the baby at 13 weeks of gestation, which is 3 months pregnant, is marked by the development of the neck, which allows the baby to move his head more easily. The head is responsible for almost half the size of the baby and the thumbs are very different from the other fingers, being easily observed in an ultrasound exam.

At 13 weeks it is common for the doctor to perform a morphological ultrasound to assess the baby's development. This examination allows to identify some genetic diseases or malformations. The price of the morphological ultrasound varies between 100 and 200 reais depending on the region.

Development of the fetus at 13 weeks of gestation

The development of the fetus at 13 weeks of gestation shows that:

The hands and feet are properly formed, but they still need to mature in the following weeks. The joints and bones are getting more and more rigid, as well as the muscles. The baby's bladder is functioning properly, and the baby pees every 30 minutes or so. As the urine stays inside the bag, the placenta is responsible for eliminating all the residues. A small amount of white blood cells are produced by the baby, but he still needs the mother's blood cells, which are passed through breastfeeding, to defend against The baby's central nervous system is complete but will still develop until about 1 year of the baby.

The baby is more like a newborn baby and on an ultrasound you can see their facial expressions. In this case, a 3D ultrasound is the best as it allows you to see more details of the baby.
