Pregnant women who fall and land on their knees are usually fine as long as there are no abnormal symptoms such as abdominal pain or vaginal bleeding. Due to the cushioning of the pregnant woman’s abdominal fat and amniotic fluid in the uterus, a fall on the knee will generally not cause a great impact on the fetus. Generally speaking, as long as there are no other symptoms such as vaginal bleeding or abdominal pain, there is no need to be overly concerned, but a repeat ultrasound is needed to check the condition of the fetus. However, if abnormal symptoms such as abdominal pain and vaginal bleeding occur, you need to seek medical attention. Pregnant women must pay attention to protect themselves during pregnancy, wear non-slip shoes to avoid falling, if inadvertent falls, it is best to seek medical attention in time to improve the relevant examination, and to do regular obstetric examination, timely detection of problems, and targeted treatment and therapy.
