Anyone confirmed multi ovulatory days or more apart?

Peartree

I am pretty sure I am multi ovulatory (as was my sister/mother) Confirmed ovulation on day 14 by ultrasound. Temps not risen yet. Pattern always 14-17 days period from final increase above 36.5c. Has anyone else had confirmation of multi ovulation by scan or bloods? (Am 46 and just off 5 yrs breast cancer treatment)
