Which OPK do I go by?
I’m a little confused. I got positive OPKs on CD 24 and CD25, the ones on CD25 looked stronger than on 24 but Glow categorized them both as strong positives, and said my ovulation day would have been CD25. But I just entered my BBT, CM, and OPK data into FertilityFriend because I read that it is more accurate in BBT prediction and it said my ovulation day would have been CD26. I thought you were supposed to go by the first day of positive OPK but is that wrong??
