Negative test or possible faint???

I'm pretty sure this is a negative test but I got a very faint postive on a cvs brand blue dye early test and then I took one of these dollar store tests yesterday and then another today but they seem pretty negative to me. What do you ladies think? I'm planning on getting first response tests and test in a few days. I am a week late so I feel like a solid line should show by now but I'm not sure. Please help!!!!!!
