Aw Choccy that sucks!! That was me last month and it's properly pants.
Barmy, hope it's just one of those weird things and AF doesn't arrive.
Good luck next month Signora - enjoy lots of festive naughtiness in the meantime! 
So after all that, I hope I'm not being insensitive. But...I think I have a BFP. In fact I'm pretty sure. The line is faint still but definitely visible without squinting or moving the stick around.
Bought a two pack of CBs for tomorrow and couldn't resist. Will do another one with FMU tomorrow to be sure!
