How many iuis are you doing before moving on

So DH and I just found our 2nd <a href="https://glowing.com/glow-fertility-program">iui</a> was a fail....so now DH wants me to put a # on how many I'm willing to do before moving to saving for either <a href="https://glowing.com/glow-fertility-program">ivf</a> or adoption. My original number was 4 because each cycle costs us around $600 total...our insurance has no infertility coverage...so <a href="https://glowing.com/glow-fertility-program">ivf</a> will be out of pocket....what is your ladies cap number our dr will let us do up to 6 <a href="https://glowing.com/glow-fertility-program">iui</a> before reevaluating...but I dont want to wait that long
