Shadow line after one minute??

Hey girls I'm completely new to any type of mom discussion board but I have a few questions. I decided to take a test and I took about eight of the first response blue dye ones that were obviously positive but it was five minutes after the amount of time suggested which I know I shouldn't look but I just happen to leave it on the counter.. and one pink dye the pink dye test showed up right away but it was from the dollar store so last night I took two and this morning I took one and a shadow line appeared within one minute so I'm wondering what this could mean ?? I'm peeing alot I have headaches everyday and I've had extremely light pink and brown blood
