Pregancy test negative then positive?

Okay so I am freaking out a little. I took a pregnancy test this morning at 4:30 to get the freshest pee possible. I waited for the test for about two minutes— i didn’t have a clock with me. It was negative. I set it aside to see if the test would change. I fell asleep and woke up two hours later and the test was positive. I heard about expiration lines. I am due for my period tomorrow. Am I pregnant?

I should mention I tested Friday with a digital and it said negative.
