Paid for an early ultrasound thinking I was 6 weeks 5 days. Was able to see a gestational sac and yolk sac but no fetal pole. Gestational sac measured 5 weeks and 5 days. Ultrasound tech said that it’s just early.

Is this a bad sign? Is it possible to be a week behind like that? Do any of you see the start of a fetal pole?
