Hi to all newbies!
Winkle thank you for letting me know, I tested in the afternoon too (just got the empty face but it's only CD6!)
Wishful I have no knowledge of the super fertility after mc, but my guess would be too that you now have more hormones than usual rallying around your body, which might help...?
Fatasbutter I too am scoffing everything which will be out of the menu after BFP -they are all my favourite foods!
Re: Alcohol, caffeine and vitamins. I think I probably drink too much. I like a glass (or usually two) of wine 4-5 times a week. I am now trying to cut it to couple of days a week only (weekends). DH probably drinks a little less (and mostly sticks to one small glass). I only drink coffee in the mornings, and take Wellwoman original which has pretty much everything in it, have not looked into individual vitamins.
At the moment (ttc cycle two) I am not trying to do anything too drastic with lifestyle (just cutting wine and cake), since DD was conceived on the same diet (I then got my BFP in cycle 4 -which was also the first cycle I used OV sticks, so knew when to jump DH!) 
That said, I am now getting older so I am fully aware that this may not be as easy as last time.
