Sorry in advance for the long post 😅

Okay, so the light green and dark green tests are the same brand that I ordered from amazon and I don’t know why they look different. They are the Proven brand and the blue are easy at home. So I did the ovidrel trigger shot on the 19th, and was told I could do opks to follow ovulation. The proven ones never got like exactly the same color, but the easy at home looked positive late on the 20th of Jan or the 21(yesterday). I ran out of the first box of proven and used the new ones starting the 21 to confirm the easy at home but they looked negative.. However the very bottom test I just took looks positive, so I tried to confirm with a first response but it was negative!!! Has anyone ever had issues with different brands? I ordered two boxes of the proven at the same time yet they look so different.. And the first response ones never got close to positive!!

*very bottom pic is the two tests on the 20th two minutes after I took them.
