Does not matter: Geeeeez…..2 days difference! either way of measuring is only an estimate. The baby will come when ready. Generally, a due date based on last menstrual period would not be changed based on a 1st trimester ultrasound unless the measurements were off by more than a week. So looks like the due date is 2/15 (did i mention it is only an estimate and the baby will come when he/she is ready!?).

Life is not exact: Life is not exact. With pregnancy dating, february 15 and february 13 are the same day... That's how life is. This is especially important to remember after the baby is born, meaning parents always should be patient and forgiving, as there are no perfect children and no exact numbers in their lives. That being said, an ultrasound done between 8-11 weeks of gestation is considered accurate.
