confused

So I know they say your not supposed to look at tests after the 10 mins but I can't help myself. The last four tests I took all different brands and all of them are the faintest of positive after a few hours. The lines actually have color and I've done both blue and pink dye. I can still look at ones from past months and they are still negative but these four all have lines! Fingers crossed for a bfp soon but what's your experience, did this happen to you and you was actually pregnant? What brand was it?
