FF wrong maybe?

Rox

Hi ladies, so this is my first month tracking BBT, and I’m a little confused. On the 5th i had my positive opk, and FF put my ovulation day on the 6th, which looks correct. Buuuut i normally have a 14 day luteal phase, temps are still above cover line, and there is still no sign of AF, also all pregnancy tests are negative, since 9dpo. Could it be that i had another lh surge and actually ovulated 2 or 3 days later ? I dont know what happening😫
