The reason why you can’t get pregnant until three months after tubal imaging is because tubal imaging requires injection of contrast material and X-ray exposure, which may have adverse effects on the fetus, and even the risk of fetal teratogenicity. Tubal imaging involves injecting a contrast medium into the uterus and then observing the tubes and uterus under X-ray fluoroscopy to see whether the tubes are open or not, and the shape of the uterus. Since both the contrast agent and X-ray have a certain degree of radiation, early pregnancy may cause miscarriage or even abnormal fetal development due to the residual radiation in the body. The residual radiation in the body can be eliminated 3 months after the operation, so it is recommended to get pregnant after 3 months. In addition, sex should be prohibited within two weeks after the tubal imaging to avoid infection, pay attention to rest, pay attention to balanced nutrition, eat more fresh fruits and vegetables. If you experience any discomfort such as abdominal pain, nausea or vomiting after the procedure, or if you become pregnant within 3 months, you should consult a doctor promptly.
