I hate those!!!!!!! I took mine and same thing happened, when I take clear blue ovulation test, I take it with other ones, all of mine other one showed super low and clear blue was giving me high and peak every time I take a test. I stopped using that cause they seem to be faulty! I would highly recommend you taking other ones just to confirm it is what it says it is.
I have used these in the past and they seem to be spot on. I since switched over to Inito to track more of my hormones. It seems to coincide with the Clearblue OPK
Not sure if it’s unusual to get peak without high fertility first. Although it’s never happened with me. You’re not supposed to test once you hit peak. Also, they’re discontinuing this digital ovulation kit and app. Good luck on your journey!!
