Digital tests all positive and test strips all negative?

[PearlSquid]

Hi all, I’ve been testing positive with clear blue since last Friday getting 1-2 weeks on all. But Tesco and other test strips all coming negative? Any reason why?

I can see the faintest line ever on that strip test. They take a while to darken up for some reason always has for me! But you’re definitely pregnant!! Congrats 🥳 x
