Confirming ovulation help please 🙏

Question re bbt to confirm ovulation…do the 3 temps immediately after ovulation have to be consistently higher than the 6 before, or can you have 3 temps consistently higher in the overall luteal phase higher than the previous 6 to confirm it? Hope that makes sense! Chart attached for reference, think I ovulated (if I did) around CD32 but temp didn’t start increasing until CD34. Positive OPKs on CD31 & 32. I have longer cycles for reference - around 41 days the last couple of months. Have attached my bbt graph from this month and OPKS.
