So when did I ovulate? Bbt chart

[MotherofBoy]

Not clear at all when I ovulated this month chart is v confusing! Ff thinks it is CD12 but it can't be as the high temp I got on CD13 was less than 12hrs after positive opk:

CD12 - negative opk at 5.30pm, positive opk at 9pm.
CD13 - high temp rise but I felt v hot in the morning so don't think this temp should be considered.
CD14 - positive opk at 5.30am which surprised me as thought I would have ovulated on cd13.

So temps above cover on 14 and 15. So did I o on cd13? Or CD14?

No, that looks fine. It may be you'll get another spike later but the pattern won't be apparent. However FF tends to update itself when it gets more information. It changed my ovulation date this month too.

If you're worried about the CD13 rise then change the time in FF so that it appears as an open circle. But in reality a difference of one day won't make much difference.

The LH surge can last beyond the actual ovulation but only for a day or so. Are you sure all three were positive? Was any one stronger than the other two?

Definitely positive - I use cb digital to avoid any confusion! Yeah I am thinking ovulated late on evening of CD13. Hence why still positive on CD14 am. Have to see what temp is tomorrow I guess
