Scan but no baby in the sack

So I went to for my scan as I have been having bleeding it’s light but the doctor said I still needed to go for a early scan. So I had the intro sound and they found the sack and no baby or heartbeat 😰 they see iv either had a miscarriage or I may not be as far gone as I thought and just can’t see the baby yet so I have to come back in 2 weeks to double check.

Has anyone else had this and seen the baby after waiting a bit longer , or sadly miscarriage?

Very scared
