02/22/2016 AT 11:00 AM EST
While Kailyn Lowry faces the impending deployment of her husband Javi Marroquin, she also deals with a heartbreaking miscarriage.
Likewise, newly divorced Leah Messer's world is overturned when she loses custody of her twin daughters to her ex Corey Simms.
Jenelle Evans continues to battle with mom Barbara over custody of her son Jace, though friction between Barbara and Jenelle's new boyfriend – not to mention an outstanding criminal charge for the assault of her ex Nathan's new girlfriend – are providing plenty of stumbling blocks along the way.
On a happier note, Chelsea Houska is still going strong with boyfriend Cole DeBoer, and it looks like wedding bells will soon be ringing.
Teen Mom 2 returns March 21 at 10 p.m. ET on MTV.
