I just started using this app last cycle. My last period was March 6th through March 10th and the app calculated my fertile days to be from March 19th through the 23rd and predicted my next period to be on April 5th. (My cycle is about 30 days. I have been logging every day and after logging today I noticed that the app switched my fertile days to this week? I don't think this is right bc I had the egg white CM on March 21st along with mild cramping on one side.  Does anyone know why it moved the dates around?
