Tracker off/wrong?


I’ve been using this for about a year now and it’s always putting me as late, and I’m always taking tests and they’re always coming up negative. Sometimes it’s as much as 12 days late and the flow is not any longer than before. I have not really changed anything. Debating on to continue/discontinue this app. It was really only so I’d know not to wear white shorts on a day that it was coming; but, now I’m as clueless as before!!

***Anyone else have this issue??!***
