8 weeks empty sac success stories

Success stories please ladies.

I just had a scan and I'm around 7+2 - 7+6 if I ovulated the day after my surge I'd be 7+6.

Scan showed sac that measured 6 weeks exactly, no baby, no yolk sac. Scan was both external and transvaginal. I have to go back in 7 days to see if anything has changed but sonographer said highly unlikely as she should at least see a yolk sac.

Please has anyone been in a similar situation at this gestation and found a baby on their follow up?
