Bad test?

Period is 3 days late. Took a test the day my period was supposed to start and got a negative. Took the second test today and still got negative (supposed to be a + when positive)
But the negative line is faint with hardly any color compared to the control line. And these pictures were right at the 2 minute mark. Does that mean it's a bad test? Or am I really not pregnant 😔 how long should I wait to test again if my period still doesn't show? These are e.p.t tests, should I get a different brand?
