Which chart?

Mrs

So my chart thinks it's likely I o'd on 25th but I think I may have actually o'd on the 21/22nd. The 22nds temp increase over the previous valid 6-7 days is 0.6

Note: I have PCOS, ovulation strips do not work for me, I've tried. This is also my first cycle back tracking my BBT after taking a break from it.
