Pregnancy Due Date Calculator Work Out Your Baby's Due Date

How to Use This Calculator

Using our pregnancy due date calculator is simple. Follow these steps:

1. Select whether you want to calculate based on your last menstrual period (LMP) or an ultrasound date.
2. Enter the date of your last menstrual period or the date of your ultrasound.
3. Click the "Calculate" button to see your estimated due date.
4. Review the result and understand the pregnancy timeline.

The calculator uses standard pregnancy duration assumptions. For most healthy pregnancies, the average duration is 40 weeks (280 days) from the first day of the last menstrual period to the due date.

How the Due Date Calculation Works

The pregnancy due date is calculated by adding 40 weeks (280 days) to the first day of your last menstrual period (LMP). Here's the formula:

If you have an ultrasound date, the calculation is slightly different. The due date is calculated by adding the number of weeks since conception to the ultrasound date. For example, if your ultrasound shows you are 12 weeks pregnant, you would add 12 weeks to the ultrasound date to get your due date.

Understanding the Pregnancy Timeline

The pregnancy timeline is divided into three trimesters:

• First Trimester (Weeks 1-12): This is when the foundation of your baby is formed. You may experience morning sickness, fatigue, and frequent urination.
• Second Trimester (Weeks 13-28): Your baby is growing rapidly, and you may notice your belly starting to show. This is often the most comfortable trimester.
• Third Trimester (Weeks 29-40): Your baby is preparing for birth, and you may experience Braxton Hicks contractions, back pain, and shortness of breath.

Each trimester has its own set of symptoms and milestones. Understanding the pregnancy timeline can help you prepare for what's to come.

Common Misconceptions About Due Dates

There are several common misconceptions about pregnancy due dates:

• Due dates are exact: Due dates are estimates, not guarantees. Every pregnancy is unique, and babies can come early or late.
• Due dates are the same as the due date: The due date is the date your baby is expected to be born, but the due date is the date your baby is expected to be born.
• Due dates are the same as the due date: The due date is the date your baby is expected to be born, but the due date is the date your baby is expected to be born.

It's important to remember that due dates are estimates and that every pregnancy is unique.
