How long does ovulation take if you release more than one egg?

I am on 100 mg Clomid to induce ovulation and I am pretty certain I released more than one egg this month. I could feel twinges on the day of ovulation (yesterday) on my right side in the morning and late that night i had the same feeling on the right side. Now today I feel twinges on my right side again! Is it possible to release 3 eggs in one cycle and if so, could ovulation last 2 days??
