Hi all I took 4 blue dye pregnancy tests over 4 days (1/day) any ways they all look like BFP except for the 1st one it's more faint but they all get darker each day. But I've heard/read that blue dye tests aren't reliable. I took a $ store test today and thought I feel I can see a Very faint line I could just be seeing things, so I would like some opinions please and thank you

P.S. yes I took them apart for a better picture cause I kept getting glares my camera sucks but all the tests were dried and the lines did not change at all....
