How many unsuccessful cycles before advancing from Clomid/Letrozole?

Hey guys!

How many cycles of Clomid/Letrozole did you go through unsuccessfully before your doctor was willing to advance to gonadotropins, <a href="https://glowing.com/glow-fertility-program">IUI</a> or <a href="https://glowing.com/glow-fertility-program">IVF</a>?

Have already had two unsuccessful cycles using Letrozole, and am thinking doc might say to try Clomid next.

Also am in the South of UK.

Thanks for your replies!
