Hello, I am confused, Ff keep changing my ovulation date.
Do you think I have ovulated when Ff says?
Thank you

Based on the temp spike, yes, FF says the right thing.. but based on your OPK result, it could be CD15. Nevertheless, either CD 15 or CD 16 is when you ovulated

yeh ur spike is saying it was day 16. the spike in temp is what confirms O happened.
