You could also subtract three months from the first day of your last period and add seven days.

When should I expect my delivery date?

Should I go by LMP or ultrasound due date?

If the ultrasound date is within seven days of your LMP date, we would stick with your LMP date. Ultrasounds done later in the pregnancy are less accurate for dating, so if your due date is set in the first trimester, it shouldn’t be changed.
