How iften would you need a saline scan (hysterography)

[Hyland]

I'm sure I had one in either June or July 2015 with the NHS and since then I have had failed ICSI privately and a failed frozen transfer.

Is my consultant just making money from me.

Making me go for the scan again and have an AMH test again which i Had privately in August which was 27!

When he told me i needed to have a scan i just thought it was a regular baseline scan rype thibg bedore going again.

Now realising the scan is actually the dye test thingy HSG.
