Has anyone measured behind at all? I’ve measured 11 days behind?

Went in at 6+2 to see just both sacs. Went back at 7+3 to see heart beat of 105 and sac and baby measuring 5+6. Dr doesn’t seem concerned but I know when I ovulated due to testing and I found out super early at 9dpo so nothing adds up and I’ve already had 2 losses so I’m so worried.
