Do the math!

Ok, put on your thinking caps, because we are going to get started with due date math! Pregnancy is calculated as 40 weeks, but it rarely ends up being exactly 40 weeks. Babies come early, babies come late. The 40 weeks is just a guideline that we use to measure.

The first thing you need to figure out is the first day of your last menstrual period. Your estimated due date will be 40 weeks from that day. It is also around 280 days from your last menstrual period, if you want to figure it that way.

Count from conception date

But, what if you don’t know the first day of your last menstrual period? Can you figure out your due date any other way? You can try to figure out your due date from the date that you think you conceived, if you know that date. Your due date is an average of 266 days from the day you conceive.

This is an alternate way to figure out your due date if you don’t know the first day of your last menstrual period. However, you should try to figure out the date of your last menstrual period, since this is the most accurate way to know when your due date will be.

Why count from last menstrual period?

Why do we figure out due dates from the date of last menstrual period? It seems like there are just too many other variables that make figuring due dates out any other way harder and more difficult to chart. However, keep in mind that your due date is never set in stone.

It is actually quite rare that you will give birth on your due date. You should only use your due date as a guideline, such as “I am due sometime around the end of June”, or “I’m due near Christmas”. This is a good way to keep you from stressing out about your due date. Just remember to use it as a basic guideline, and not a rule.
