Hi, I took a hpg yesterday around. 7pm-8pm it looked negative but something kept catching my eye and I've just looked at it now (5am) and there's a very very faint line with a hint of pink but my camera can't pick it up.. Does this sound like its positive?! I've just took another but again it looks negative but I saw a line for a few secs before the ink dried but then it went! I don't believe in the "only read within 5 mins" because it took 3 hours for my positive to show with my lb and they were strong lines x
