A CT done one month before pregnancy may adversely affect the growth and development of the fetus. CT is a radioactive test with a low radiation dose, which has some adverse effects on sperm, eggs and the gestational sac in early pregnancy, and may affect the growth and development of the fetus, and may even lead to malformations of the fetus. However, if all the tests are normal when the pregnancy test is conducted regularly, it means that the growth and development of the fetus is normal and it is possible to continue the pregnancy. If you have had a CT in the month before you get pregnant, and you find that there are abnormalities in the fetus during the pregnancy test or that the pregnant woman is experiencing abdominal pain during pregnancy, it is recommended that you seek medical attention in a timely manner, under the guidance of your doctor, to complete the relevant examinations, clarify the cause of the disease, and provide symptomatic treatment.
