HI, it's hard to say if you actually O'd or not. You have two open circles which means those temps may not be accurate and you could have O'd sooner than you FF says if you did in fact O. The only way to be sure if you have LPD (luteal phase defect) is with blood work (checking your progesterone level) and with an endometrial biopsy)
LPD There is an article on LPD through JM.
I don't know if I helped you make a decision on whether or not to try next cycle or temp another cycle, but I hope I did give you some info. Good Luck!
