It is usually possible to get pregnant one month after a CT, and it is recommended that you have regular checkups. It is true that CT may cause some radiation to the body, but the effect of the radiation on the quality of the fertilized egg is uncertain, so if you find out that you are pregnant one month after having a CT, you can observe the pregnancy for the time being and have regular check-ups. If the pregnancy is already confirmed, CT is usually not recommended. During pregnancy, you should pay attention to avoiding laborious work, and relax and do not have too much stress. You can go to the hospital for a Down’s syndrome screening between 15 and 20 weeks of pregnancy, and go to the hospital for a four-dimensional ultrasound examination between 20 and 26 weeks of pregnancy. It is recommended to go to the hospital in time after finding out that you are pregnant and check all the indicators of malformations, and the final recommendation for fertility should be based on the indicators of the examination and the doctor’s judgment.
