Question about glow- updating period cycles

Emma
Hello lovelies 
​My period is usually about 7-12 days long (lucky me) and this month I went over by 2 days so I edited my cycle in glow but it hasn't amended my "fertile" days.
 I finish my period today and it is still showing me as fertile tomorrow for the next 7 days.  
​Should this be right? 
​Also, glow still asks me to measure my cm and cervix position when I have my period does everyone else do this?? 
Thanks xx
