Dating Scan

idkwhatmyusershouldbe

Hey ladies! So I was told GSA is 7 w 1 day but this is start date of last period, my OB said they are exactly the same. So would i technically be 5 weeks and 1 day? Are the 2 weeks for gestational age calculated into the dating scan? They’re saying baby is measuring 7 weeks 1 day as well but I was on my period and didn’t have sex until 2 weeks after my period. This is confusing, can someone help?
