Ovulation test help!

I use the easy@home test strips and we are currently waiting to do our first <a href="https://glowing.com/glow-fertility-program">IUI</a> cycle completely medicated. I was told to start testing on CD 10. I started on 9 as a baseline but I got a peak yesterday and today the lines are much lighter... my cycle is typically 28 days. I called my drs office both yesterday and today because we were thinking we would do the insemination today. But my normal nurse is out and this other nurse keeps telling she thinks my strips are wrong... anyone have any thoughts?
