8 week baby as big as 10 week per the tech

River

Hi ladies,

I just came back from my 8 week ultrasound and the technician said the baby looked like 10 weeks. I am very confident about when the baby was conceived. And the due date was calculated by the doctor. The tech said that the baby is bigger and the due date might be pushed up. Is this normal? Has anyone else experienced this. I am of course freaking out about what can go wrong... any advice?

Thank you!
