Faint positive?

I know many will say I shouldn't as it's not entirely reliable..but I have taken a pregnaxy test (one that states can be taken up to 6 days before the misses period) as I'm just so curious! I have two sons already whom I fell pregant with first try, and so I feel it's impossible to be three times us lucky! However, lately my husband has been saying I 'have that look my eye I get when pregnant' lol I'm six days from my missed period but I see a very faint second line..what would your opinion be? Am I just wishful thinking?:))
