How many cycles of HCG trigger shots did you do?

For those of you ladies who have done cycles with the trigger shot and timed intercourse at home...how many cycles did you do before doing a more aggressive approach like an <a href="https://glowing.com/glow-fertility-program">IUI</a>? I got my second trigger shot a week and a half ago but I'm not so sure it worked this time either. I'm only 24 so we are trying not to do anything too radical since I'm still pretty young, just curious what other people's experiences are...
