If an X-ray is taken without knowing the pregnancy, it is advisable to terminate the pregnancy, because X-rays have a strong radiation effect on the fetus, which may cause fetal malformation and affect the development of fetal cartilage. It is recommended to go to the Department of Eugenics and Obstetrics for further consultation, with the aim of understanding when the last menstrual period occurred, how many days of pregnancy the x-ray was done, how the examination was at that time, the length of time the x-ray was done, and to make a comprehensive analysis and evaluation to decide whether the pregnancy should be terminated. Sometimes it is necessary to make a more comprehensive decision depending on the individual situation.
