question on ultrasound?

If they say you are 7 weeks does thar automatically mean you conceived at 5 weeks even though you know you don't typically have a 28 day cycle?

Also she said they did it off both lmp and measurements because I was unsure of lmp

    It's dearly impossible to figure out exactly when you concieved unless you know the exact date because cycles vary so much. I can tell you they always go with ultrasounds though.

  • Yes - if the scan dated you at 7 weeks then conception occurred 5 weeks ago.
