Teen Mom 2 star Leah Messer has suffered a miscarriage. It was recently announced that the 19-year-old mother of two was engaged and pregnant with her fiance Jeremy Calvert's baby. Unfortunately a source told OK! magazine, "She was having bad cramps for the past two weeks, and then she miscarried." Calvert said, "All I can do is support Leah and take things day by day. It's hard, but we will get through it."
