Faint lines don’t get darker??

So I’ve had extremely sore breasts and frequent urination. Every pregnancy test I’ve taken the past few days has a faint line but they don’t get any darker. What could be going on. Here are some tests.

I mean you see those too right?? Why won’t they get darker? I’m going crazy. Is it possible I just happen to get every single test that’ll show me a n indent even when taken in time frame?
