Low BBT, late ovulation... help!

I've been tracking using Natural Cycles for about a year on and off, decided to switch to FF last month to get more accurate data. This month was a crazy long cycle, I didn't ovulate until CD36 (cycles are usually 31ish days for me), and now my BBT seems to be sitting around covering, when usually it would be higher? Anyone have any idea wtf is going on 😅 Do I still have a chance this month? (Well.. over 2 months really!) OR is this just chaotic enough to call it out.... P.S I know its unlikely but I have been having cramps and really sensitive/sore nipples the last 24 hours which has never happened before. Very chaotic time in my brain haha.
