So I tend to ovulate a few days later in my cycle then expected. When I track the symptoms, then glow will alter the green days when I am ovulating. However because I'm a few days later then my period gets pushed back a few days on the calendar. How do I correct this? My cycle is super regular. Every 31 days like clockwork. Now every month I have to go in and count the days to figure out when I should actually be expecting my period and if it's late (or even better, doesn't show at all!)
