You might want to make sure your tubes are free of blockage to avoid another ectopic
pregnancy, because when you have one
ectopic pregnancy, your risk to have another increases. I had one (an HSG) done in 9/07. I asked for it. Your MD will not automatically suggest it, you must be proactive. A hysterosalpingogram is an Xray done where a catheter is placed in the internal os of your cervix and advanced to your uterus. Then there is a contrast dye injected through the catheter.
