There are several ways to check the fallopian tubes: 1. To know whether the fallopian tubes are open or not through the method of tubal imaging, it is often possible to do the tubal imaging test only after not having intercourse within the 3rd-7th day of the menstrual period, after the outpatient checkup, and through the normal conditions of leukorrhea test, blood routine test, and coagulation time check. Tubal imaging test can find out whether the fallopian tubes are open or not, and find out the development of the uterus. Because the tubal imaging test is carried out under the X-ray, so it is not possible to get pregnant within three months after the operation. 2, in the ultrasound under the instructions of the tubal fluid test, fluid test can only understand the tubal passage or not, but it is difficult to understand the specific obstruction site through the fluid test, so it is best to do the tubal imaging test if you have the conditions.
