Positive and Negative pregnancy test.

Is it possible for digital test to be wrong? I took a pregnancy test when I first woke up this morning and it has a faint positive. (My period is still 7 days away) so I took a digital one a few hours later to be sure that I wasn’t seeing things and it said I wasn’t pregnant.

I posted my first morning pee test. This is the line I got and like I said it’s 7 days until my missed period. There’s definitely a high chance that I’m pregnant. I’m going to test again closer to my period, but I was just wondering if I can still be pregnant with a negative digital test.

*Note: this test turned positive before the 3 minutes was even up!*
