Teen pregnancy is epidemic, we know. But what about fake teen pregnancy? A 17-year-old high school girl in Toppenish, Wash., surprised classmates at a student assembly this week when she revealed that she was not six months pregnant, as pretty much everyone except her immediate family and boyfriend and the school principal thought she was.

Gaby Rodriguez faked her pregnancy as a “social experiment,” according to the Yakima Herald Republic. And she found that, in general, teen moms faced a lot of stereotyping and hurtful attitudes.

Gaby began wearing a homemade prosthetic belly to school after spring break. Before that, she wore baggy clothes to conceal her faux pregnancy.

“In essence, she gave up her senior year,” said Principal Trevor Greene. “She sacrificed her senior year to find out what it would be like to be a potential teen mom.”
