iui with clomid

L

So first time doing <a href="https://glowing.com/glow-fertility-program">iui</a> with clomid. What ovulation sticks do you ladies use , I use clear blue digital usually. I was told to call the day I get a positive ovulation so I can come in and get my trigger shot. But with clear blue do I call in when I get a blinking smiley or a solid ?
