Walmart HPT

How many of you guys use the Walmart cheapies? Does it usually take a while for the line to form?

I’ve been taking them for a few days. Like 10dpo-13dpo. The line shows up really faint in the first 3 min. By 10 min, there is no doubt a line there consistently for 4 days. But the fact that it takes 10 min is making me crazy.

Has this ever happened to you? Is it normal?

I was reading reviews on Walmart website and it seems common.
