Pregnant again after 21 week loss

Viviana • My wife & I are pregnant at the same time with our rainbows, a little boy & girl. We lost our first at 21 weeks (IC).
Hi y'all. I lost my firstborn last year on thanksgiving day at 21 weeks. (Subchorionic hematoma that resolved itself at 13 weeks but then I pprom'ed due to incompetent cervix) He was born alive and perfect but because he wasn't "viable" at 24 weeks, I held him until he passed away. 
I'm pregnant again and while I'm so excited, I'm terrified I won't get to keep this baby either. Anyone have tips on how to face the fear and overcome it? I'm trying my best to remind myself how this pregnancy is different and declaring it'll be healthy.
