A member asked:

Can you tell me how precise is a transvaginal untrasound at determining conception and due date?

Dr. Stacy Yamasaki answered

Specializes in Radiology

Pretty good: The dating is accurate to about a week as long as the sonographer can see the baby early on. The due date though is really variable.

Dr Maes and another doctor agreed
