There is a possibility that early menstruation may be caused after tubal imaging examination. Tubal imaging is an examination method that injects contrast into the uterine cavity and fallopian tubes to observe the morphology of the uterine cavity and to check whether the fallopian tubes are open or not. Due to the stimulation to the uterus during the operation, and if the patient has heavy psychological burden and emotional tension, it may lead to early menstruation, and it is normal to be early for up to 7 days in general. Tubal imaging is usually performed 3~7 days after menstruation, for patients with vaginitis and pelvic inflammatory disease, the test can only be performed after the inflammation is under control, and those who are allergic to the contrast agent can not perform the test, and they can not have sexual intercourse within half a month after the test. For infertile women, if they need to improve the tubal imaging examination, it is recommended that they go to the gynecology department of regular hospitals and actively treat under the guidance of doctors.
