The journey of pregnancy is filled with anticipation, and one of the first questions many expectant parents ask is, "When will my baby arrive?" Determining your expected date of delivery (EDD), also known as your due date, is an important step in planning for your baby's arrival. While it's just an estimate—only a small percentage of babies are born exactly on their due date—it provides a valuable timeline for your pregnancy.

Calculate Your Due Date Now →Methods to Find Expected Date of Delivery
Several methods can help you estimate your due date. At pregnancy-calculator.org, we offer a comprehensive tool that utilizes various inputs to give you the most accurate estimate possible:
- Last Menstrual Period (LMP): This is the most common method. It calculates your due date by counting 40 weeks (280 days) from the first day of your last period.
- Conception Date: If you know the exact date of conception, you can use this to calculate your due date, which is typically 266 days from conception.
- IVF Transfer Date: For pregnancies achieved through In Vitro Fertilization (IVF), the transfer date provides a precise starting point.
- Ultrasound: An early ultrasound can provide an accurate estimate of gestational age, which can then be used to determine your due date.
Our Pregnancy Calculator and Ovulation Estimator combines these methods for a personalized timeline and predictions to help guide you through your pregnancy.
Using the Pregnancy Calculator & Ovulation Estimator
Our tool at pregnancy-calculator.org isn't just a pregnancy calculator; it also functions as an ovulation estimator. This dual functionality allows you to:
- Pregnancy Calculator: Determine your due date, track your current trimester, and key pregnancy milestones using your last period, conception date, or known due date.
- Ovulation Estimator: Pinpoint your fertile window and ovulation day based on your cycle length, complete with an interactive six-month calendar that color-codes your period days, fertile window, and peak ovulation day.
Factors Affecting Your Expected Date of Delivery
It's important to remember that your due date is an estimate. Several factors can influence when you actually give birth:
- Cycle Length: Women with cycles longer or shorter than the average 28 days may have their due date adjusted.
- First-Time Pregnancy: First-time mothers tend to deliver slightly later than those who have had previous pregnancies.
- Ultrasound Measurements: Early ultrasounds are generally the most accurate for dating a pregnancy. Later ultrasounds are used to monitor growth, but are less accurate for predicting the EDD.
- Individual Variation: Every pregnancy is unique, and some babies simply need a little more or less time to develop fully.
What to do After You Find Expected Date of Delivery
Once you find expected date of delivery and have an estimated due date, it's time to:
- Schedule your first prenatal appointment.
- Start taking prenatal vitamins.
- Begin making healthy lifestyle choices, such as eating a balanced diet and avoiding alcohol and tobacco.
- Start thinking about your birth plan.
And above all, use the time to mentally prepare to start your amazing pregnancy journey!
