I took this and didn't even look at it after a second line didn't show (so over bfn's!) came back 15 mins later and just thought I'd pull it out of the trash and look just in case (gross I know- I do it all the time). I am 2 days late and I know it was 15 mins later rather than 10....should I go and re-test??? I don't want to get my hopes up!
