Are these opks getting darker?

[Aph413]

Using the clear blue digital opk tests. These are getting darker right? Feel like I'm going mad checking for lines. All giving a high reading apart from the first.
Hoping I get my peak reading soon

don't stress too much if you don't get your peak, I didn't and still got my bfp.

Thanks scared it's just the expectation that I should be getting one that's setting me on edge
