So I was using the regular clearblue opk the last 2 months and decided the splurge and get the clearblue advanced opk for this month.. on cycle day 13 it said I was high which Day 16 on the app was my ovulation day.. I took the advanced opk on day 17 just to make sure since I never hit peak and it just kept reading high so I tested again today and still high (never hit peak) I ended up taking the regular clearblue opk and it said low.. I’m so confused?
