Maybe Pregnant?

Okay. I took a pregnancy test this morning. AF is due today and no symptoms have occurred. I took the test about 9am and it said negative. My husband sent me a picture of my test and it showed positive. I don’t know what to think so I took another one and it’s negative...could it be because the test hanged over time or am I getting ahead of myself? My real question is that is it possible if a test sits to long can it change to positive from negative? Here is the test.
