Check Out The '16 And Pregnant' Season 4 Trailer [Video]

On the heels of the roller-coaster ride that was "Teen Mom 2" comes Season 4 of "16 and Pregnant," and by all accounts, it is the most heart-wrenching installment yet. Beginning Tuesday, March 27, with two back-to-back episodes, MTV once again explores the harsh reality of unplanned pregnancy in its groundbreaking documentary series. You'll meet 12 new girls struggling to relinquish their youth and prematurely take on adulthood with a baby in tow, many times without a supportive boyfriend or family. The challenges they come up against at times feel insurmountable--one teen will even face the tragic death of her fiancé.

Take a look at the show trailer for an introduction to some of the stories you'll see unfold every week. While the teen birthrate is down, teen pregnancy is still a huge issue in the United States, and hopefully this continuous exposure to its hardships can serve as an educational aid and deterrent.
