What detection setting is everyone using on their FF app for accurate results for them??

My cm signs, opks and temps are not matching up and its so confusing!!
According to FF advanced setting my temp says im CD5, but my cm has been creamy for close to 2wks now, so it seems unlikely to me I ovulated 5 days ago.
My watery fertile cm matches up with my +Opk making me CD15 if i go by opk detection but there was no "3 day high temp" correlation.
Whats going onnnnn!!
If it happened when I think then were in with a good chance this month. If its the 5 days ago then we have no shot this time around so im worried we missed it!
