very confused… need opinions

I’m so confused on how I ovulated on cd 10. I thought your next three temps had to be higher than previous 6 in order to confirm ovulation & my temp on cd 11 was not higher than my temp on cd 5. I put my temp in today and ff calculated that I ovulated on cd 10. I swore I probably ovulated on cd 11 due to cramping on my left side on that day and the fact that my temp hadn’t really risen yet. is this chart calculation accurate?
