Help?!?!

Pi

Posted on another page but I’m freaking out right now I don’t know what to think. Yesterday I took a test, got a SUPER light pos, like hubby & I could see but didn’t picture well. Then this morning I took a test and got a much more obvious pos... in the 3 min mark, got a picture, then a min or two later I went to look and it was gone? What does that mean? (Test behind is from yesterday)
