Can someone help with this calendar

A • Jesus is my savior.
Hi! I'm not sure when I'm supposed to be ovulating by my calendar.  I have two showing different days. Glow shows oct 5th and my <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation calendar</a> shows the 9th. When should I baby dance with my hubby?
