Gestational sac & yolk sac size @ week6

Hi all, I'd like to know your gestational sac and yolk sac size at week 6. My doctor mentioned mine is small and may not be viable so I'd like to know the average size at week 6. Thank you.

I did an abdominal ultrasound at 6w, and CRL was about 0.33cm! But not too sure how accurate it is cos it was so early…. At my 8w scan, CRL increased to 1.52cm!
