Confused and feeling a bit disheartened

Teneale β€’ Never ttc again but we're ready for baby #2 😊
I'm 26 and SO is 28. Been ttc for 7.5 months. Last month glow told me that I ovulated cd23 and it came up on my bbt chart. This month this is what my bbt chart looks like during fertile window just wandering if you know why it hasn't said I've ovulated?? This is going on from further confusion about fertile period changing mid way through. Really havnt done a lot of bd'ing this month 😰
