Praise for what it's worth I never got a full on dark one but think I missed the surge and was picking up the build to the surge
So I tested this morning at 2.30 when middle one woke me up as he needed loo
Just ic and I dipped and left it
Forgot about it then went back and there's a faint line on it
So did another 1
And it was working very slowly (pink was still moving up so not completely clear yet) and that looked like a very faint line was forming too
I've read a few times that ic take a bit longer to show up
Also don't want to get my hopes up
And like a mad woman will prob test once I've held wee in for a few hours lol
