During the Season 3 finale of Teen Mom 2, we learned that Leah Messer took out her IUD and got pregnant again — this time with now-husband Jeremy Calvert. Unfortunately, she miscarried the child back in January 2012 after experiencing mysterious cramping for a couple of weeks.

Obviously, Leah and Jeremy were devastated by the loss, details of which will most likely be revealed during Season 4 when it premieres on February 18.

Thankfully, Leah had her sweet little twin daughters, Aliannah and Aleeah, born on December 16, 2009, to help keep her spirits up. And though she and Jeremy were not married when she suffered the miscarriage, they have tied the knot since then and are looking forward to expanding their family. In fact, Leah just gave birth to a healthy baby girl on February 4, 2013!
