Thank you keep us in your prayers.
Hopefully it will work it self out, but from my personal experience I went for an 8 wks check up with my 3rd pregnancy and the baby was only 6wks1day in size, but still had a good strong heartbeat. Unfortunately is died that day and by the time I went in a week later there had been no more growth and not heartbeat. I will pray that is not the case with you but I would try to prepare yourself just incase.
