I work as an xray tech and have not only done these (with the assistance with of the MD) but have had this done on myself. I see you have plenty of information from the receiving end, but do you understand WHAT they are doing? Or the reasons behind it?
You are in an xray department with an xray tech and MD. The md does ALL the work, under sterile environment as the technologist comforts you and gives you information. I highly recommend taking either tylenol or motrin BEFORE your procedure because you will experience some discomfort.
While on the table, the MD will use a speculum, much like at the OB office and use a tiny plastic canula into your uterus. He/she will inject some very THICK iodine contrast (shows up bright on xrays) to visualize the tubes as well as the dumpage of contrast into the pelvis. That is where the cramping comes in. It is from the contrast. Try to take nice deep breaths and visualize someplace nicer.
The MD may have you roll side to side, to better visualize the tubes and if there seems to be a blockage, they may even have you roll onto your stomach. Dont be alarmed.
That should be the entire exam. You may have cramping throughout the day as your body absorbs and expells the contrast. You may have some bleeding. All normal.
And yes, many woman become pregnant AFTER this study because yes it is at times, theraputic.
On the receiving end of this, i think EVERYONE gave you great information. I experienced cramping but it was much like menstral cramps.
I wish you luck
If you have any questions, please ask.
