Finding out that you are pregnant after having a single X-ray is usually possible, but if you have multiple exposures, it may have an effect on the child. Fetal abnormalities caused by X-rays during a woman’s pregnancy depend mainly on the gestational week as well as the radiation dose, while a single X-ray exposure has a very small radiation dose for a relatively short period of time, which is relatively safe and generally does not affect the fetus. So if you find out you are pregnant after having an X-ray, the baby can usually be kept. The 2-4 weeks of pregnancy is a teratogenic sensitive period, when cell division is active, and if a large number of X-rays are irradiated, it is easy to cause miscarriage or teratogenicity. So if X-rays are done multiple times during this period, they may have an adverse effect on the embryo. Pregnant women who continue their pregnancy need to do regular labor and delivery checkups, and at the same time relax their mindset and don’t be too nervous.
