So what is the difference between “high” and “peak” opk. I use pregmate. I log them on this app and also fertility friend. From my understanding your first positive is the one you go off of, then no need to test but of course I keep going to watch it fade.

Do you ovulate 12-36 hours after high if you get a peak the following day? I will usually get a positive opk where the lines are equal then sometimes the following day is blazing positive, even darker than the control line
