Pregmate pregnancy tests sensitivity???

Destiny • 🤩 Destiny 🤩

Quick question , are pregmate pregnancy tests not as sensitive as others ??

I'm only asking because I'm concerned or I got a bad batch . I've had positives on different brands (3) to be exact and I'm getting like a shadow on the pregmate I'm so confused ! I read on the instructions it's most accurate the day after your missed period ?? And I'm 2 days away from expected period .
