The first pick is at just over 3 mins and secound at 8mins. My test said wait at least 3 mins to read and 10 for full results DO NOT READ PAST 10. Im thinking ➕. So do I still test tomorrow? Im new to this OPK thing wanted to try for a month or two see how close glow was on my green days seeing as I still haven't conceived. Glow says 5 test=80% accurate 10=90% accurate. But when so I take them till it fades. And if it is positive does that mean next month (if this isnt my lucky month) I start opk earlier. I was only On my first green day by glow.
