Thanks Mary, I am still surprisingly positive, after the initial slump I felt earlier today.
My mother, bless her, had tackled my mountain of ironing by the time I returned from bf'ing DD earlier, so I didn't have to face that after AF turned up
not that she knew anything about that - only my sis and DH in RL know we are ttc. And as sad as I felt initially, I am definitely counting my blessings 
We've just had a family movie night with The Croods and treats, and, sat there with DD, DH and my 2 cats I already feel so blessed to have what I have. Another amazing dc would be a bonus, and I'm sure it will happen for us, it's just a matter of when. I'm thinking I should be pg by May / June as this is my silly deadline, and I've never missed a deadline in my life 
If it doesn't happen by then though, well, I have a very happy, clever DD who gets to spend some more undivided time with us until she's a big sister 
Cue my many questions and random musings over the coming months if I'm to go back to trying to make sense of my opks though, sorry in advance
