NT at 12 weeks of pregnancy

NT is a physical examination that pregnant women need to do. Many expectant mothers will choose to do this examination at 12 weeks of pregnancy, because during the examination they can detect the baby's height and physical condition. At the same time, they should pay attention to fasting on the day of the examination, cooperate with the doctor during the examination, and expectant mothers should also relax and not be too nervous.

Generally, after 12 weeks of pregnancy, a second ultrasound examination can be performed on an empty stomach on the same day. If the fetus is growing well, a perinatal manual can be created, and laboratory tests such as routine blood tests, blood type, liver function, blood sugar, urine routine tests, as well as blood pressure, height, uterine height and abdominal circumference can be done at the same time. It is recommended that the handbook be established in the hospital where the household registration is located. Pay attention to filling in the relevant information in the handbook and establish a complete file to facilitate systematic examinations during pregnancy.

This week, the baby is about 9cm long and weighs 23g. The fetus's life-sustaining organs have begun to work, such as the liver has begun to secrete bile, the lungs have been fully formed, the thyroid gland and pancreatic islets have been fully formed, the liver has begun to produce blood cells, and the kidneys have secreted urine into the bladder.

The skull halo is clear, the biparietal diameter can be measured, obvious deformities can be diagnosed, and the internal organs tend to become more complete afterwards.

At this time, the growth rate of the fetus's head begins to slow down, while the growth rate of other parts of the body gradually accelerates. The fingers and toes have completely separated, some of the bones have begun to harden, and the rudiments of joints have appeared.
