Find out your due date with our Pregnancy Due Date Calculator.
Based on a 28-day menstrual cycle we use Naegele’s Rule, is a standard way of calculating the due date. Actually about 2 weeks later is when you conceive (your pregnancy date is 2 weeks behind your fetal development).
First day of the last menstrual period (LMP), count back 3 months, add 7 days and add 1 year
LMP: December 18, 2018
If you were tracking your ovulation and you know the day you conceived, we can calculate your due date by counting 38 weeks from that date.
