It's time for the second mandatory screening. Indeed, at this time it is possible not only to distinguish individual parts of the fetal body, but also to “see” its smaller structures: details of the structure of the vertebrae, brain, heart. The data obtained will allow the doctor to draw conclusions about whether the child is developing normally. Starting from the 22-24th week of pregnancy, 3D ultrasound can also be performed. Three-dimensional reconstruction will allow you to form an idea of the baby's appearance, look for the first similarities with mom or dad, and help the doctor get a complete picture of the development of the fetus.
