The best time to have a tubal imaging is 3-7 days after menstruation and without intercourse. Before the imaging, we need to check the white belt routine, gynecological examination, blood count and coagulation time, and only if all of them are normal, we can do the tubal imaging. The main purpose of tubal imaging is to understand the development of the uterus, whether there are longitudinal septa in the uterine cavity, and whether the fallopian tubes are open. Tubal imaging is usually performed 3-7 days after menstruation and without intercourse. If there is any clinical obstruction in the fallopian tube, it will be seen very clearly by the imaging. The patient should be observed for 1 hour after the imaging and should leave the hospital only when there is no discomfort. After the tubal imaging, the patient should keep the vulva clean, no sitz bath for 2 weeks, and no sexual intercourse to avoid infection, and no pregnancy for 3 months.
