Thick Evap Line?

Now I don’t want to hear about not looking at tests after the 10 minute mark please 😂😂 I have taken many pregnancy tests in my life & have seen many evap lines especially from the Walmart cheapies. I took a test yesterday, a little bit after I took it I looked at the test again for shits and giggles. This is the first time I’ve ever had an evap that wasn’t a skinny line. The evap line is as thick as the control line. I could be anywhere from 6 DPO-10DPO it’s hard telling. Thoughts ??
