Concerning?

Hi y’all! I’m 4w5d today and I had my confirmation appointment yesterday. Well I bought a 3 pack of FRER bc they are so much more sensitive than the cheap strips I got off amazon and during my last pregnancy I got a line progression and that was super encouraging to see. Welllllll.... last night I took a test and test line was darker than control line and that’s great! Well this morning FMU I got a test line and control line that are almost the same... kinda concerning me I guess. Anyone have any insight? I know I’m a crazy person lol

Top is this morning FMU and bottom is last night about 9pm.
