A HSG (hysterosalpingogram) is an xray of the inside of your fallopian tubes and uterus. First you are asked to lie on an xray table with your knees bent, just as you do for a PAP test. Then a speculum is inserted into the vagina. Then a thin tube is inserted through the cervix, and contrast is put into the uterus through the tube. xrays are taken, and the images are displayed on a monitor. An HSG usually takes 10-20 minutes. You can probably return to work right after your HSG. You may have some cramping and a thick discharge for a few hours. Use sanitary pads, not tampons, until the discharge is gone. Your health care provider will most likely also tell you not to have sexual intercourse and not to douche for 24-48 hours.
Call your health care provider right away if you have bleeding, pain in your abdomen, or a temperature above 100°F. Your doctor will discuss the results of your HSG with you after the radiologist has looked at all the images.
