@Chalkie67 I find the easiest way to switch off has been not to do the testing/app tracking and then just not in your head every single day! I genuinely have only thought it probably every other day this month so far (cd13/14ish now) where's usually it's multiple times per day.
I figure I track enough months to roughly know my cycle now, and going for the every other day method now! For a bit anyway.
Fingers crossed for us all 'not' TTC @Aokbaby @Florence13 too 
Ok this is a bit of a personal one, but one thing I've been finding myself wondering recently is whether 50% of the time OH doesn't, you know, do what's needed to conceive. He says he does (I haven't asked him, he just always says when he's in the moment...!) but then afterwards I haven't felt anything, no damp patch or wetness, at all. This is probably 50% of the time, and the other 50% I can definitely tell because it's everywhere...
If it is the case, I certainly think it could be due to the pressure of TTC as I've only noticed this in the last few months and it has turned DTD into a chore and a pressure. I haven't raised it, and I don't think I will, because if it is psychological mentioning it will probably make it worse. I'd rather first try and subtly put the fun back into things...
I suppose my question is, do you think sometimes OH can do what's needed and it be not much or not feel it? I suppose he could be, he tends to stay in for a minute or so after so maybe it just all goes where it needs to.
I've just really noticed it recently, and I suppose if that's not happened then it's definitely not going to happen!!!
