Pregnancy found after having a chest X-ray may lead to the occurrence of embryonic abortion, spontaneous miscarriage, abnormal fetal development, and an increased chance of fetal developmental delay due to a decrease in the quality of the embryo. It is not 100% that the fetus is found to be abnormal after a woman is found to be pregnant after having a chest X-ray. If a woman is pregnant and then has a chest X-ray, there is no lower abdominal pain, vaginal bleeding and other cases of pre-eclampsia or embryonic abortion, and the woman has high expectations for the fetus, she can also observe first, and later strengthen the maternal examination to do early Down’s screening, amniotic fluid testing, and ultrasound for teratology, and if there is an abnormality, it is possible to deal with it again. If the pregnancy is found after the chest X-ray and the woman has a preterm miscarriage or embryonic abortion, she needs to be given an early termination of pregnancy, possibly due to radiation-induced spontaneous abortion caused by the chest X-ray.
