why did the app do this?

so the first picture is my last two periods and the second picture, I still never got my period. the last time I was three weeks late it just kept pushing it back, but this time it's just blurred out the one I was supposed to have and the next one. my questions are 1. why did it stop pushing it back like last time? and 2. why is my next predicted period blurred out as well? is it because I haven't entered in a test or is there another reason? any help is useful thank you in advance.
