A member asked:
Do you really need to know your lmp or is a dating scan an accurate enough way to see how far gone you are in pregnancy?
A doctor has provided 1 answer
US is enough: An early dating scan in the first trimester of pregnancy is quite accurate for determining how far along someone is in her pregnancy. It is especially useful for those who are uncertain of their LMP or who have irregular cycles. While not exact, the dating scan is usually accurate within a few days of the actual gestational age.
