Are they getting darker?

I got a faint positive at 11dpo and have been testing everyday since. AF is due tomorrow so I am not getting my hopes up yet. They are both with fmu. The odd thing is the blue ones are supposed to be "high sensitivity" and the wondfos are darker. First pic was yesterday and second is this mornings
