Second round of IUI

I will be trying a second round of <a href="https://glowing.com/glow-fertility-program">IUI</a> after first failed. Does anyone have any advice about what worked? I'm trying to increase my chances. I'm so nervous..my first <a href="https://glowing.com/glow-fertility-program">IUI</a> was unmediated. Doctor wants me to try at least 3 times before starting any meds.
