Tweak needed, please!! This is not fmu second test today. This is our last iui, but I think this is darker than this mornings test!! Please help

First 2 test are now 3rd one is from this am. I wanted to make sure it wasn't a faulty test, decided to test again in the afternoon. I think it seems darker? Or am I just going mad? This is our last <a href="">iui</a>. We have been trying for our rainbow since our loss last November.
