Ovulation? LH surge but no BBT rise?

[Runner1234]

Hi 😊
So from last month we are TTC. I came off the pill in Jan and didn’t get a period until May. Since August my cycles have been 33-35 days whereas in May /June they were looking like 29. This month my ovulation has come 5 days early, I had the biggest LH spike I’ve had and yet my BBT has barely risen in comparison with the last two months. Does this look normal? First graph is this month and second is last month. Thanks for your help!

I would assume you have had a failed attempt at ovulation and keep DTD as it's likely your body will try again. This is pretty normal.
