Please help - freaking out. Frer test and control line darker on top than botttom.

Ok, so this is my 5th IVF cycle and my last. Hubby is done trying. I really need this cycle to work....

Yesterday (11 dpo) line showed nicely on Frer and pregmate. Today pregmate got darker (second pic) but Frer looks lighter. When I look at the Frer more closely - I see the top part being darker than the bottom. When I compare the top portion of the Frer to yesterday it seems it progressed. Am I going nuts? Probably. I just need some reassurance that this test may just be faulty??? Anyone experienced this and got darker lines again the next day? Blood work is not until Friday. I am a mess. 💕
