Clomid question please please help

Jessica • Tue, May 26 • Pregnant with my first baby boy and due on November 16th :). Pro-lifer :)

My SIL started taking clomid on May 2nd and that was the 3rd day of her cycle when should she have ovulated ? She's been having vaginal pain lately but it's been 2-3 weeks since she stopped clomid and her period stopped ?
