Pregmate strips

Hi everyone, for educational purposes for anyone who has Pregmate strips, I wanted to post this. I’m 5w1d. I tested 2 days ago and found out it was positive. The top is a pregmate brand, bottom is 1st response. The pregmate brand took literally 3 minutes to show a line and it’s definitely more faint than the other. I’ve taken about 10 others and had the same experience. If I had only had this brand and checked it before the 5 minute mark like I usually do, I would’ve thrown it away thinking it was negative because the line took forever to show. Even yesterday the lines were about half as dark as other brands. Not sure if it’s just me but if you don’t wait the full time, you could mistake it as a negative.
