GLOUCESTER, Mass. (AP) -- A pregnant high school student in Gloucester (GLAH'-stur), Massachusetts says there is no pact among girls to have babies.

Appearing on ABC's "Good Morning America," 17-year-old Lindsey Oliver disputed her principal's headline-grabbing theory. Gloucester High School Principal Joseph Sullivan was quoted in Time magazine as saying girls in the New England fishing town had made a pact to get pregnant and raise their babies together.

But Oliver insists that "there was definitely no pact." She says a group of girls who were already pregnant decided they were going to help each other to finish school and raise their kids together. Oliver calls it "coincidence," and says her pregnancy was unplanned.

Gloucester Mayor Carolyn Kirk also denied a pact existed after a closed-door meeting with city, school and health leaders yesterday.
