How do I fix my predicted cycle?

I see I can adjust my period prediction but I need to fix the ovulation prediction! According to Glow I already ovulated but out of curiosity I started taking ovulation tests and turns out I am about 1 day away from ovulation! I have tested for 3 days now and opks are getting darker I just never logged them on the proper days because I was so sure I had already ovulated and didnt want to throw the app off... (since you're not supposed to opk test after you ovulate). I hope this post makes sense... because I can fix the ovulation prediction I cant really estimate when my period is due so I know when to test. I have PCOS and not being able to fix the whole month of February is becoming confusing.
