No, it means that on CD 13 the LH surged and you will ovulate in the next 24-36 hours. You should have noticed that you also have EWCM on CD13, CD14 and maybe CD15.

The lh surge starts building in the morning and so by afternoon it is concentrated and the OPK can detect in your sample.

When I was charting, I got + OPKs on 2 days, usually.

@GrannyPantiesRock:  I got 2 days of + (morning, evening and next morning) on the Clearblue digital smiley/no smiley OPK’s. I switched to Wondfo and now I can see that the First two are darker than the control whereas the last ‘+’ one is only equal to the control, so while techincally +, not really + for me. I think I O the first day or overnight between the two days of the +/almost +  OPK’s based on charting.
