Accuracy may vary: A careful transvaginal (not transabdominal) pelvic sonogram (a "first trimester dating scan") performed by a certified sonographer using a well calibrated machine and proper scannig techniques is usually quite reliable and fairly accurate (plus or minus a few days) in dating your pregnancy. A follow up pregnancy sonogram in a few weeks should help answer your concerns and confirm your dates.
