Slow pregmate progression??

T • Mama to a miracle🌈 6/8/21

I’m confused!! Yesterday I started getting vvvvvfl on my pregmate tests (I took 3 spaced out throughout the day)

Are these known for awful indents?? Or is progression just slow with these? This is my first time using these strips.

*update- diff brand test just taken, posted at bottom!!
