Glow is wrong!

Bailey • TTC for baby #1 for a year and a half. One ovary. Praying for my blessing!
I'm a consistent 31 day cycle. Well I believe I ovulated on CD14 or 19. Glow is telling me it was on CD24 which puts me at a 37 day cycle, which is wrong! I know my body. I should be starting tomorrow but my chart temps are staying elevated. Is this a good sign?!
