How many IUI's did you do?

C
<a href="https://glowing.com/glow-fertility-program">IUI</a> #2 just failed. AF showed today. 😔
My dr wants me to try 3 <a href="https://glowing.com/glow-fertility-program">IUI</a>'s and if we are 0/3 he wants to move on to <a href="https://glowing.com/glow-fertility-program">IVF</a>. 
How many <a href="https://glowing.com/glow-fertility-program">IUI</a>'s have you tried? Any Success? Is there a step I can take between <a href="https://glowing.com/glow-fertility-program">IUI</a> and <a href="https://glowing.com/glow-fertility-program">IVF</a>? 
I wish I knew why this wasn't working. 😔Â
