I'm sure that she said they'll figure it out is because most times they can based on the ultrasound. Try not to worry! Those first ultrasounds are considered very accurate for determining gestational age based on crown-to-rump measurement. The baby grows so much in the first trimester that it is calculable to determine age reliably by that measurement. Hugs!! When is your appt scheduled for?
