One thing I do wonder ...
Once you do a test and the line shows for negative, or two for positive, will they stay around longer if you are
a) pregnant
b) not pregnant
I was wondering this because if it's really hard to tell if the second line really exists, then if the darker line stays there for longer perhaps I may be pregnant. If both dissapear (even the second line that I think I see but maybe dreaming about!) then I'm off to have a wine and nice slice of Brie Cheese tyvm!
