Clomid

Leah
Just had my 2nd scan on clomid and im about to ovulate todayy!!! 2 follicles one at 19mm and the other at 16mm. Doc says the 16mm one will ovulate in 2 days. And the 19mm one any time now! Whats the chances of twins? Is this like a double chance for me to fall preg this month!? Any success stories?
