How to Determine Your Baby’s Due Date
Did you just find out that you’re pregnant? Congratulations! Pregnancy brings a lot of excitement and joy, but can also be filled with worries, questions and discomfort. One of the biggest pregnancy questions? The due date. The question everyone (including yourself) wants answered the minute you find out you’re pregnant.
Pregnancy is calculated based on the average menstrual cycle, which lasts 28 days. The first day of menstrual bleeding marks the first day of the menstrual cycle, called your LMP or last menstrual period. When calculating the weeks of pregnancy, include the two weeks from the first day of your LMP—where the beginning of the menstrual cycle and your pregnancy is measured from. Your estimated due date is calculated as 40 weeks from your LMP.
Your due date is estimated at 40 weeks—280 days—to the approximate first day of your last menstrual period.
When was your last menstrual cycle? Add 7 days to the first day of your LMP, then subtract 3 months
Here are a few pregnancy calculators we recommend:
Using a pregnancy calculator will not only show you your due date, but will give you an entire calendar that you can print out with the major milestones of your pregnancy by actual date. A pregnancy calculator will help you to see when your weeks go by and when you hit big milestones like the first heartbeat, baby movement and more.
Using a pregnancy calculator and calendar will allow you to track:
- Pregnancy stages
- Follow your baby’s development week by week
- Find out what changes you can expect in your body, your emotions and your life
