Has anyone ever used clinical guard?

Elizabeth • Mommy of 6👧👧👼👼👼🤰🌈baby due september 29th, but should be coming any day!!!

I ordered some clinical guard pregnancy test strips off Amazon to track my line progression. Has anyone ever used them? I got my first BFP with a frer yesterday, so i want to track progression until I can get in to see the doc. How well do these work?
