Edit ovulation in glow?

Debi • Ttc #2
This is my first month using Glow. It rod me that last week was my ovulation, but when I'm not on the pill, my cycle is wacky. After charting all my stuff, especially my CM and cervical position, I know I did not ovulate last week and am pretty sure it's happening right now (horrible cramping, very different feeling of the cervix, CM more eggy!) is there a way to edit that in glow, or does it change the data based on when I get my next period?
