Wtf one hella of a positive and one barley positive

So I took 2 tests being cd34 of what should have been a 30 day cycle and having been having some weird red spotting but no af I decided to take a pregnancy test was absolutely shocked when I saw it was blazing positive as I’ve had ZERO symptoms and I always believed I would do it took a while to appear like that dark started off faint and just kept getting darker and darker so I ran out and bought some first responses and well... I had to tilt it in the window and everything just to see the line once it was first done, it’s still a squinter the top blue dye was taken at 9am this morning the bottom one was 7pm I just carnt believe the contrast between the two has anyone had this happen before? I’m so confused right now which one do I believe luckily it came in a 2 pack so will retest on cd37/38 see what I get
