I'm 5 dpo. I do opk, bbt charting, cm & cp checks daily. Fertility friend & Glow both state that I ovulated on the 20th because of my temps (I have 4 consistent high temps higher than my pre ovulation temps) & everything else recorded. I had a couple OPK left so I decided to use them just to use them post ovulation but I'm 5 dpo and they're still resulting in strong positives, they are all equal but mostly darker than the control line. Do any of you know what would be caused by? Did I not ovulate on the correct day? I know some have said it stays positive for a while but I thought they would be at least fainting by now
