Cycle Prediction inaccurate

Kristin

Earlier last year my cycles were irregular, but for the past 6 months (after using a vitex tincture) I now have had regular predictable 31-32 day cycles, the glow calendar hasn’t picked up on this regularity and is still predicting my next period will be later (it’s predicting a 35 day cycle) is there a way to reset this or get it to be more accurate?
