I tested positive on Monday, took 3 more test just to be sure and all came back positive. I took another pregnancy test yesterday and it came out positive but im looking at it now and it faded 😕 so I took 2 more right now and they came out positive. What is going on??

The first picture are the ones I just took now. The second picture are the ones from Monday, but the blue dye one is the one from yesterday that was sooo positive but now looks like its faded. Could it just be the dye??
