You ovulated on cd 14. I agree with pp, your temp doesn't rise until AFTER you have ovulated.
Your temperature will spike approximately 24 hours AFTER ovulation HAS occured. If ovulation does not occur a temperature spike will not be evident.
You have a rise in temp the day after you ovulate, your temp goes up and stays up or starts to drop right before your period.
i would say CD 15 because that is the day of the rise, usually you can't tell on the day you ovulate by the temperature that is why on FF it is a dotted line because it is possible it was the CD14 but i think its the 15.
as far as I understand the day before the rise.
