“Just add 7 days to the date of the first day of your last menstrual period (LMP) and count back 3 months.”
Example: If your LMP is January 16, then your EDD is October 23.
How to compute?
Month: January minus 3 months equals October.
Day: 16 plus 7 equals 23.
Remember: These dates are not 100% accurate. Your baby may arrive two weeks earlier or later than the EDD.
