clear blue easy advanced OPK question

C
Hey there-
For anyone who has used the OPK mentioned above, I got the peak fertility indicator yesterday morning. It seems that indicator stays on the display for 48 hours and that you do not need to test while that is displayed. Just wanted to ask if this is the same thing you all are doing?  Would love to hear if anyone successfully conceived using this one too and how long into using it that it happened. Thanks!
