Change in BBT jump month to month?

This is my second month charting. Last month, my cycle was super long thanks to a follicular cyst - that’s why Glow’s predicted O is so late.

FF thinks I O’d on Friday, but I was expecting a bigger jump based on last month. Even though it was a long cycle, I saw a 0.6 degree jump to LP last month and this month the “jump” is much smaller.

Anyone who has been charting longer know if the size of the jump is generally the same month to month? Or if there’s any noticeable phase change, did O happen? Thanks!!
