Incompetent cervix / preterm labor

Samantha
My previous pregnancy ended at 25 weeks due to a weak cervix and preterm labor... My twin boys only made it two days and then passed away. I'm now pregnant again and 7w4d. I'll have a cerclage placed after 12 weeks and have to take progesterone shots from 16 weeks on... I'm really nervous about this pregnancy and don't want to suffer another loss. 
Is anyone else here early in their pregnancy and already thinking about their cerclage and all of that? Do you have a cerclage or plan on getting one? 
Good luck mommas!!
