The first test was taken 4 days ago it’s old now and it took a bit for the color to get darker as it dried

Took another test today with FMU and got a shadow right away, then it turned to a darker pink color

It’s been exactly 2 weeks since having sex, do the lines have to be darker for a digital to pick up the HCG??

First test all the way dried

Second test after 60 seconds

Test now
