Basicly i took a test this morning thinking that although i feel pg in not due af yet so thought even if i am it wont show, bur did a test anyway cus im impacient 
So.anyway i did the test but then forgot about it and left it on top of the loo for an.hour.
When i checked it i saw in the light a very faintest of faint lines in the test box!!
My question is, is that test now invalid and proberly not a bfp cus i left it too late to look at??
