@ohiwishyouwerehere that's perfectly normal. I had an early scan at 5+2, and it was the same. They don't expect to see much at this stage, but by 7 weeks there should be a blob with a heartbeat. When is your rescan?
@bluebell94 I don't plan to tell work until after the dating scan. I have a history of miscarriage, so even though it will probably be obvious (it was last time) I will be keeping quiet.
@Persiaclementine I know what you mean about it feeling 'wrong'. My MMC last year was the same, but this one feels 'right'. I guess time will tell.
