Clear blue advanced digital HELP!

Emma • Mama 🐻 pregnant with #2
Hey ladies, this is our first month TTC and I picked up some clear blue advanced digital. I know- expensive. But sometimes knowing is worth it. But I have some questions for those of you who have used it. I'm pretty regular and have 35 day cycles, give or take a day. I have been testing the last 4 days with this test. Day 1, nothing, day 2,3 and 4 I got high fertility but have yet to hit my "peak". What is going on?! And day 2 my cervical position was optimal (in my uninformed opinion) PLEASE HELP!!
