Ladies, I have to thank you all for giving me a good laugh over the last couple of days reading this thread, I'm loving the positive POSITIVE attitudes! 
I'm on cd 26 of a 27-28 cycle, I use opk strips and got a positive for a surge on cd 12. I have no symptoms of anything, but then I haven't done for any of the 6 months we have been TTCing for. I'm ancient, (38 in a couple of months) and trying for #1, but I think this may be the month - I'll tell you why....
Our flat has been on the market since Feb, we had an offer but it fell through because they thought we had damp. We had it investigated and it seems it's not damp, it's actually a burst water pipe. So what's the problem? The problem is that the pipe is embedded in a concrete floor (it's a basement flat) and it's looking like the whole floor in both the living room and the only bedroom is going to have to be broken up to get at it. It could also prove rather expensive and wipe out a large chunk of our savings we wanted to put towards a new house... DH is so strung out about it he can't sleep (although it hasn't affected his, ahem, performance
)
So..... it really couldn't happen at a worse time! It's inevitable that THIS is the month the egg will finally stick, when our flat is uninhabitable and we spend all our money fixing it up, don't you agree?
