At what follicle size you Ovulate

Friends

I want to know at what follicle size you ovulate if you are monitored by ultrasound. Both medicated and non medicated cycles. As i have a doubt my ovulation occurs at a follicle size less than others.

On clomid -i ovulated when my follicle sixe was 21 in the evening and HCG injection was given in the morning when the size was 20

I had only one US monitored non medicated cycle and in that i ovulated when my follicle was only 17 mm.

:drowning

This cycle again i am without any medications and will have a scan on CD 12.

 

Thanks Vasu,

waiting for more input from other members.
