It's because you're so excited! But the ic that I use are wondfo. It seems like a lot of women trust that brand. I've been doing some reading and it's really not good to test before 11 dpo, even with a first response. The chances of getting a false negative before that are really high. The chance of getting a false negative before AF is supposed to show are really high too, and if you test the day AF is supposed to show the line is still going to be faint. No matter what the brand you're using is. It's typical to not get a very noticeable line until a few days after AF is supposed to be there.
