Hi all, can I join? I've been following this thread and trying to SMEP each cycle (on #7 now!) but not quite getting it right due to one reason or another. Still managing lots of DTD round fertile time though, so always gutted when AF arrives 
So this month I'm trying it properly - and DH has promised he'll try harder after seeing me so upset at AF last month - bit like you and your DH, fiddle.
However... Best laid plans and all that... we DTD CD8, 10, 12, then I got my pos OPK on 13 but made the executive decision NOT to DTD as I was going away over night CD 14.
Therefore if we'd done it on night of +OPK, I wouldn't have been able to do it again til cd15, and I usually ov on 14.
So I though it best to leave it cd13 and do it in the morning of cd14 before I went away. As it is, that was only 12 hours after my +OPK, as I tested late in the day, and even then it was only after the full 10 mins I realised it was +
Hoping against all hope I got in in time.
FF has put my ov date as cd 14 - despite no temping?! So that means we DTD on morning of ovulation, plus 2 days before. We'll DTD cd 15 & 16, then 18 maybe? Then I've kind of followed the SMEP, just maybe 12 hours out...
Oh god. Just reading that back, I'm full on crazy still, aren't I? I said this cycle I'd stop the craziness and stopped temping and everything! 
If you got this far, thanks and well done! Have heard so many SMEP success stories, fx for some on here soon!
(Congrats Rae! I think we were on a different bus together at one point?! I used to be nenehooo?)
