Why are all my pregnancy tests coming up after 3-6 minutes?

As you supposed to read a PT within 3 minutes of taking it, I hardly get a line where you can barely see it sometimes my mind just plays tricks on me.

But after the tests completely dries and has been like 10-15 minutes later. You can visibly see the line.

If my calculations are correct i should be 4 weeks. I feel that i am pregnant but these tests are making me doubt myself.
