Oh Rubgy01, I do sympathise! I've had that happen too. It is so frustrating. I wonder whether it he might 'behave' better if he didn't know when in your cycle you are? I ask because sometimes I think knowing might put pressure on.
Just a few days ago H was being a right arse and I was feeling annoyed/ anxious because it was CD 9 and time for whispering sweet nothings and not his man-tantrums about whatever ridiculous nothings
. I sometimes think he is more likely to throw a wobbler around this time of the month because he thinks I'm more keen to smooth things over. But I have been opk-ing with CB and had a clear circle that day so I let him stew (in the spare room). He apologised in the morning and nothing to do with the flashing smiley I got so I 'forgave' him! 
I started opk-ing last month and it was a disaster - I started too late, did it all wrong once (out of practice, I hadn't done it in a while), ejected the stick too soon another time by mistake, and didn't bother trying later in the day as CB always worked before for me with fmu. So when I didn't get a smiley I didn't know whether it was because I am a clutz or because I am now a barren old lady in her mid forties and I'm not a drama queen obviously.
So this month I was delighted to get a flashing smiley on days 10,11 & 12, and now a static smiley on day 13. And DH (he's 'D' now again) didn't even need any prodding for dtd! He performed his husbandly duties with aplomb!
I am hugely relieved that this suggests I might still be ovulating after all, as I was stressing about that. When my cycle was 28 days, I always got a static in CD 14, so I guess a static smiley on day 13 fits with a 26 day cycle.
ababs I've started reading 'It starts with the egg' and am a bit
at the contact with chemicals chapters. I wondered if that is why you were trying 'method' floor cleaner?!! I ask because I went out earlier this week and bought a lot of Method cleaning products!! I've also ordered a load of 'natural' shampoos/ body creams etc. It's compelling stuff, that book!
