How long does it take for the baby to die?

How long the fetus will die lying down sleeping, this is not sure, but pregnant women do not lie down sleeping. Because lying down sleeping easy to press the aorta, affecting the placenta blood supply, long time, easy to lead to fetal hypoxia, intrauterine distress and even fetal death and other symptoms, therefore, pregnant women had better prevent lying down sleeping. In the second and third trimester of pregnancy, pregnant women's sleeping position should be mainly on the left side, which can correct the increased uterine rotation, but also ensure sufficient blood supply to the placenta to ensure normal fetal development. If the long-term left side of the body is uncomfortable, you can adjust the sleeping position appropriately, but on the whole, you should adhere to the left side, so as to reduce the symptoms of oppression.
