I'm confused

Ladies I took a test on Friday because AF was supposed to start that day. It was positive after exactly 3 minutes. I included the picture below. It's now Sunday and still not AF. It's 10 DPO if I counted correctly. I just took a clear blue test because I heard the curved ones can give false positives. It says not pregnant. I included the picture. What does this mean? I'm so afraid that's something has happened. My fiancé and I were so excited to see the positive result. I can't even think of calling to tell him about this one until I have some answers. (He's currently serving in Korea). Can anyone help with this? I'm a mess.
