CB OPKs

[Hopefulhedgehog]

Using CB OPKs - the pink more basic ones which only have a static smiley. The past 2 months I have had 2 static smileys (CD11 and 12) and then the 3rd day (CD13) I have my temp rise that morning. I am trying to work out timings for DTD. I know O can be 24-36 hours from LH surge but I’m wondering whether to count that from 1st or 2nd smiley? We have DTD on CD8, 10 and 11. We could do with a night off tonight but I’m wondering if CD13 will be too late?

I think it's counted after your last smiley. Previously I have been dtd on those two smiley face days. Last month I felt ovulation pain the day after my last smiley face and I though that's strange as i now have an empty circle. But I now know it's usually the day after your last smiley you ovulate? This month I'll be waiting until the last smiley and the day after as so far dtd prior hasn't worked. X
