nervous 😩

Need to calm my nerves! I have my scan on Friday I'll be 11+5 had early scan at 6 weeks was all fine. Feel like it's been so long in between. Can't be exited about it I feel like something will be wrong. Wonder if my baby is growing properly.. if there's a heartbeat ect.. hear to much of these silent miscarriages and I'm petrified! Just want Friday over and done with😩😔
