Femvue?

I called today to schedule my CD3 bloodwork and SHG and the nurse mentioned they would do the Femvue test at the same time as the SHG.

From reading on the internet, it's like the HSG in that they are looking at the tubes, but they use saline and air to accomplish it instead of the dye, and it's done in the RE office by the RE.

Has anyone had the Femvue done? If so, what was your experience?

The more I read, the more terrified I get. I can't get it done til Jan b/c my dr is on vacation through New Year's so I miss my window. I'm hoping I get PG this month and it sticks so I don't have to do this!
