Getting sick of the glow calender

I ovulate early in my cycle. I get a positive opk on day 10 or 11. And my cycles are between 26 and 30 days on average.

so why?? is it predicting a 34 day cycle with ovulation on day 20?? for any of you just relying on the app to estimate ovulation and help you get pregnant I urge you to use another method as well

I tried for 3 months with the app and nothing. then 2 months with opks and got pregnant but miscarried in june. going on to month 6 and definitely using opks as I would have clearly missed my window based on the app.
