What do u do after a m/c post IVF

Our first IVF worked, pregnant with twins and right when I was starting to let my gaurd down and think maybe everything will be fine, went in for an u/s at 13 weeks and no heartbeats.  They said heartbeats stopped a few days before bc they measured at 13 weeks.  Had a d/c a few days ago and trying to recover.  Grieved a lot and prayers to help send our little ones to heavan.  So, now what?  I am going to see the doctor tomorrow and hoping for a solid plan to help us focus on the future.  So many ups and downs- you really gotta be strong mentally and physically for this stuff.   Good luck everyone, I hope it is in the cards for us all.
