I would say you Oed CD13 and I think that is where FF will put the CH for it too.
Did you have any EWCM that day ?
If not then you would have Oed really late CD12 and missed the temp hike.
Some people ovulate late at night and do not have enough progesterone in their blood to elevate their temps yet so it shows for the day after.
I do not think you have missed it, I think you have got it spot on.
good luck!
