The time a woman takes to prepare for pregnancy varies depending on whether the contrast medium taken for the tubal imaging is radioactive or not. If the contrast agent is not radioactive, such as ultrasonography, you can get pregnant 1 month after the procedure; if a radioactive contrast is performed, it is recommended that you wait 3 months after the procedure before getting pregnant. Tubal imaging is one of the more common tests and how soon you can prepare for pregnancy after an imaging test depends on the type of contrast. If you choose ultrasound contrast, you can use ultrasound to check the patency of the fallopian tubes, so this type of imaging is not radioactive. If you choose to have a radiographic contrast agent and observe it by X-ray, even if the test result is negative, it is recommended to conceive 3 months after the procedure. However, clinical studies have found that some women who received a radioactive tubal contrast examination had an unplanned pregnancy 1 month after the procedure and it did not affect the growth and development of the fetus. In addition, if the tubal imaging test is abnormal, contraceptive measures and further clarification of the etiology are needed.
