IUI - in the U.K.

Charlotte
Just wondering if there is anyone else on here doing <a href="https://glowing.com/glow-fertility-program">iui</a> on the NHS in the U.K.? 
And how soon it started ? 
I rang and they told me the clinic was to full this month and to call again next month. 
Wondering if this has happened to anyone else ? 
Thank you
