At 28 weeks’ gestation, the fetus is about 35 centimeters in length, 25 centimeters in parietal length, and weighs about 1 kilogram. The skin is pink, the subcutaneous fat is relatively small, the limbs move well, there is respiratory movement, the surface is covered with fetal fat, the pupil membrane disappears, and the eyes are half-open, and the fetus can survive after birth, but it is prone to Idiopathic Respiratory Distress Syndrome (IRDS). At 28 weeks of pregnancy, all the organs of the fetus have developed, and from this point onwards, it enters the late stage of pregnancy. Pregnant women should usually pay attention to the observation of fetal movement, if you find frequent fetal movement or the number of fetal movements significantly reduced, you should go to the hospital for examination in a timely manner. If preterm labor occurs at 28 weeks of pregnancy, the fetus may survive, but it is prone to idiopathic respiratory distress syndrome. Therefore, once the symptoms of preterm labor occur, you should consult the doctor in time to avoid preterm labor.
