Going For our 6th IUI

DM
My amazing husband and I have been trying for a little over 3 years...I have had 5 <a href="https://glowing.com/glow-fertility-program">IUI</a>'s and will be going for our sixth this month...the first <a href="https://glowing.com/glow-fertility-program">IUI</a> we tried clomid but it worked to well and gave me a cyst on each ovary and since then I have been taking femara/letrozole with the trigger shot (ovadrel) anyone have any suggestions on what we should maybe try differently this time to raise our chances a little bit since it is our 6thim afraid if this one doesn't work he will want us to move on to the <a href="https://glowing.com/glow-fertility-program">IVF</a> which we won't be able to afford so I am willing to try anything to make this work...any different medicine we should ask about?!
