Ovulation bbt off by a day or late ovulation??? When did I ovulate?

[Confusedmum33]

My chart changed this morning after inputting bbt from my watch that tracks overnight. When did i ovulate because I thought it was the 13th now it's changed again??

I agree that CD13 looks most likely. Does your cm normally tie in with your bbt? If so I'd assume you just have a slow rise this month.
Bear in mind that wearable bbt is least accurate.

Ahh okay thank you...good to know if did think maybe my watch was a bit out as my handheld thermometer wasnt giving me readings that high. I have had tons of cm more than I think I have ever had since then and ov test confirmed peak which wouldn't match as far as they have pinned new ovulation. Guess it's just a waiting game now 🤞. Thank you for your reply. Xx
