Hi,
Welcome to ehealthforum,
The effects of the radiation on the baby/fetus depend on which area of body the x-ray was directed as well as gestational age. The rays focused on one area usually do not get dispersed to other areas which are not in focus. Request to have the safety vest to be given to you during the x-ray, and you will be fine in protecting the baby. The radiation dose involved in a single diagnostic procedure does not threaten the wellbeing of the developing fetus. Exposures to less than 5 rads has not been associated with any fetal anomalies or pregnancy loss. You can also consider visiting the radiologist to discuss about the radiation dose used. Drink plenty of water and maintain good nutrition. Take adequate rest. Be in regular follow-up with your gynecologist/obstetrician. Get an anomaly scan done after completion of 16 -20 weeks of gestation to rule out any anomalies/birth defects in the baby.
Take care.
