Whether a pregnant woman needs an ultrasound immediately after a fall depends mainly on the severity of the fall and the subjective feeling of the pregnant woman, usually as follows: 1. Minor fall: If the fall is only minor and does not directly hit the stomach, and there is no obvious abdominal pain and vaginal bleeding after the fall, this situation is mainly based on observation, observing whether there is abdominal pain, vaginal bleeding and changes in fetal movement. Generally speaking, it is not necessary to do ultrasound immediately; 2. Severe fall: If the external impact is relatively large when falling, or if it directly hits the abdomen, and if there are obvious clinical symptoms of abdominal pain and vaginal bleeding, it is necessary to do ultrasound immediately to determine the condition of the fetus, and to exclude placental abruption, premature rupture of the fetal membranes and other conditions that endanger the life of the fetus and the pregnant woman. During pregnancy, women are often inconvenienced because they cannot maintain a normal posture when moving around due to their enlarged abdomen. Daily necessities, stairs, bathrooms, etc. should be done to prevent slippery treatment. Don’t scatter small stools, toys, or other items, and try to put them away. During the late pregnancy, you should pay more attention when you go out, and try to go to less crowded places to prevent collision with others and accidents. When you go out, try to go with your family or friends so that you don’t get confused and don’t know what to do in case of an unexpected situation.
