Test line darker than control on pregnancy teat

Does the test liner ever get equally as dark as the control line on the cheap amazon test strips? I started testing on Tuesday and my line has gotten darker everyday except

Today and yesterday were pretty much the same. Do these test ever get much darker than this one? Thanks! Had a miscarriage in September and I’m so nervous!!
