Thanks for your respones.

My wife is a bit concerned about the pain that could be experienced. She read on some websites that if the the tubes are blocked in some way, there is pain experienced during test.

She had a dermoid cyst removed when she was 26 and therefore there could be a higher chance of having a blockage.

Some people believe that after this test if there was a light blockage, this could be cleared after the test and chance on conceiving will be improved in some way.

Not sure what to believe at this point...
