Sac and Yolk but no baby - 7 weeks

Just writing this to see if anyone else has had the same experience…

I went for a private scan at 7+3, they could see a sac and egg yolk but no baby or heartbeat so I was referred to the early pregnancy clinic in the NHS.

They saw me the day after my private scan and scanned me again… they saw exactly the same as the private scan.

They can’t tell me anything yet and have suggested another scan in 2 weeks to confirm if it’s a miscarriage or I’m earlier than I thought I was, however the dates do work out (I did ovulate on date 17) but they confirmed I should still be around 7 weeks and a baby and heartbeat should be there. It didn’t sound positive I know they have to tell me worse case and I’m accepting of that but a 2 week wait sounds torturous especially when I know deep down it’s bad news. Just want some comfort, some stories and just positive comments to perk me up. I’m accepting it is what it is and some things are not meant to be but I keep breaking down in tears and feel embarrassed.
