Worried after clear blue digi

I'm in such a panic. I took a clear blue weeks indicators test last Wednesday, so 9 days ago when I was 4 weeks 2 days pregnant. It came up as 2-3 weeks which I was pleased with. I took another today so I should be 5 weeks 4 days pregnant, 9 days after the first one and it still says 2-3 weeks. I know people have said sometimes peoples don't read 3+ even when they are but I've used these tests before and they have always shown 3+ at the time they should.

I'm so nervous now. I'm going to buy some more but don't know when to test again. Maybe leave it until Monday when I will be 6 weeks?
