Wondfo tests

Megan • Trying for our third! First baby a miscarriage, chemical then rainbow. Second baby 9 months of trying 4 with clomid. Hoping for a quick easy pregnancy for #3
Has anyone else noticed there wondfo test not getting darker? I took a test on wed evening and noticed a faint positive today, Sunday evening the test is still very faint, my target early response seemed a little darker and I got a digital to take in the morning. Do you think this is normal?
