Changing cycle length?

Is it possible up change my calendar based on a typical cycle length to predict next period?

It keeps saying 41 days cycle length but my last few cycles have been 63 days (I had a baby oct 19 and before I got pregnant my cycle was 61-63 days) so I know this is *my* pattern - but I know glow works from averages - however my average has fluctuated since I had my little one and has only settled back down the last 8-10 months.

I’m hoping to TTC but I don’t think my ovulation window is correct because it keeps going off a 41 day cycle? I’m learning to track ovulation other ways but would be handy to have glow keep pace with me? Thanks in advance for any help 😊
