Dr. Robert Killian answered

Specializes in General Practice

Being Pregnant: In reality this is not common or normal. Thus most of us here would defer to your OB to explain this. You are correct. The early ultrasounds are usually the most accurate for dating. There must be a reason and i would direct you to your OB to confirm why this was done in your situation.
