The development of the baby at 13 weeks' 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 and are easily seen on an ultrasound examination.
At 13 weeks it is common for the doctor to perform a morphological ultrasound to assess the development of the baby. 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' gestation
The development of the fetus at 13 weeks of gestation shows that:
- Hands and feet are properly formed, but they still need to mature in the weeks to come. The joints and bones are getting stiffer as well as the muscles.
- The baby's bladder is working properly, and the baby pees every 30 minutes or so. As the urine is inside the pouch, the placenta is responsible for eliminating all waste.
- A small amount of white blood cells are produced by the baby, but it still needs the mother's blood cells, which are passed through breastfeeding, to defend against infections.
- 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 one can observe his facial expressions. In this case a 3D ultrasound is the best since it allows to see more details of the baby.
