Problems with chart

Sandra
Hello! Yesterday my cycle chart said that my las fertil day was Monday 24, today it says that my last fertil day was Thursday 27. I don't know what Bottom a pushed but it doesn't agree with my period. I counted the days and my ovulation day was on Sunday 23. Can you help me? Because I don't know what happened. Thx
