Ultrasound will just be an estimation based on the size of the baby. You can go by your LMP for your due date.

They can be off.



There have been a lot of these posts today... there is no way to know when you actually conceived.

They can be off. Same goes for using your LMP. Your due date and conception date are just estimates. Early ultrasounds are usually more accurate though.
