Do dating scans date from conception
The embryo still can’t be seen at all at this early stage.
By 6 to 7 weeks, it’s usually possibly to see the fetal pole, the earlier sign of the developing embryo, within the gestational sac on transvaginal ultrasound.
Failure to see the heartbeat at this stage may indicate an abnormal pregnancy.
Due dates based on high-tech ultrasounds will help doctors in deciding things like when to induce or to administer steroids or other drugs in at-risk pregnancies.

I didn't think anything of it, because I am almost 38, and this has never happened to me before.
So, my question is, when I went to have my ultrasound, the sonographer did 2 measurements for the conception date: one was 6 weeks and 3 days, and the other one (just to be sure) was 6 weeks 5 days.
When I went to the doctor I had no idea what to tell them when they asked how far along I was.
