Ovulation not showing

Jessica • It`s that girl Jess 🤓 9.28.10 ❤️ TTC for about 5.5 years now.
I can't find my original post but this app is starting to make me mad. It's not telling me when I should be ovulating... It's my third month with Glow. The first month I had a period and ovulation showed. The second month I missed my period. Now the 3rd month I had my period but it's not showing when I should be ovulating...
